🐞 [BG] Update 10/22/2024 broke our "Nude/bathing Outfit" because it broke "Outfit Generation". -- [7/14] 🚧 Post still needs overhaul.

🐞 STATUS -- OFFICIALLY UNRESOLVED ⋆ [🌐] EA Forums ⋆ [🌐] Answers HQ

🐞 RELATED BUGWATCH -- Update 7/10/2025 broke "headwear" (hats). [🌐]

↪️ WORKAROUND -- My BAND-AID still works for the underwear. "Nude" mods can also BAND-AID the issue, and I think I'm going to remake my "NudePart Override".

🚧 Bear with me, I haven't figured out the formatting for this post yet.

☆ // ⋆ SUMMARIZED BUG DESCRIPTION:

EAxis broke something concerning "Outfit Generation" in Update 10/22/2024.

The most visible result is that the Nude/Bathing Outfit now generates with the "default" underwear for the specific sim.

It's much worse than that though.

This affects all sims of all ages, including Townies / NPCs.

☆ // ⋆ MY ASSESSMENT OF UPDATE 10/22/2024:

After days, upon weeks, upon months of my own investigation, I think I finally understand what happened in Update 10/22/2024.

EAxis appears to have changed the code controlling "Outfit Generation", and now the Nude/Bathing Outfit cannot use the "NudePart" CAS items because they are no longer considered "valid".

Every Sim's Nude/Bathing Outfit is now generating (for the first time) or re-generating every single time the Sim's outfit changes - manually by clicking on a Sim or dresser and selecting "Change Outfit..." or automatically whenever the game changes our outfits, e.g. when going for a jog, to shower, to sleep, to work, etc., et cetera.

This is why resetting the Outfit with Lynire/LMS' "Reset Bathing Outfit" is temporary - it's temporary because the Outfit is constantly regenerating itself with the wrong CAS items!

Here's what's not broken, that everyone thinks is broken:

• "Default" Underwear

• CAS

• Saving and/or Resuming the game.

It's also not a custom content issue, though CAS items with improper "Nude" Outfit TAGS will result in similar shenanigans.

☆ // ⋆ UPDATE 7/10/2025 JUST MADE IT WORSE:

My "Everyday Outfit 0" has a hat. From my limited troubleshooting, I can tell you that it doesn't matter if I'm wearing "Everyday Outfit 0" or any of my other outfits that don't include a hat when I "Change Into Nude". My hat from "Everyday Outfit 0" appears on my Nude/Bathing Outfit and doesn't go away.

Resetting the Nude/Bathing outfit with either my "XMODTko" or Lynire/LMS' "Reset Bathing Outfit" mod does not remove the hat.

<HEAVY SIGH> This !@#$ has been broken for almost NINE (9) MONTHS, and instead of fixing it, they break it more!

👹 SEVEN (7) WEEKS and THREE (3) UPDATES later, it still hasn't been fixed, but they had time to work on a new FOMO Event, right? Priorities, baby!

Patreon doesn't like that link because the word NAKED is in it. I can swear all I want and I can type uncensored derogatory words, but the word NAKED?! Nah bruh, I just crossed a red line! 😹😾

──── ⋆⋅🦄 I'M NOT DONE YET, AM I?

I'm awake and working on the "NudePart Override".

B.T.W. I was right! It was "EnterBathing" or something related to "EnterBathing" I was just focusing on the underwear and "EnterBathing" angle so much that I hadn't considered they might have broken all automatic outfit switching.

There's actually a couple more things I can do, but one would be very invasive and it would break the "flow" of the game.

1️⃣ I can remove the automatic outfit switching from most actions that currently have it. It won't unbug your save, it won't fix your busted Bathing/Nude outfit, but it'll prevent a new save from getting bugged... if I can root out all instances of it. It's a really dirty band-aid, but it could be done.

You might have missed it, but I mentioned removing the outfit switching after having a jog. When you queue the action it changes your outfit to Athletic, and when you complete the jog, you change out of your Athletic outfit, I nuked the latter, so sims remain in their Athletic outfits after jogging. I'll share this SOON™.

2️⃣ Aside from the "NudePart Override", I can try to mod in that bit of code I mentioned that will force the Bathing/Nude outfit to reset itself before equipping. I don't know if the code is compatible, so I can't say for certain that it will work until I try.

──── ⋆⋅⚡ 24 HOURS LATER - I'D GIVE YOU POPCORN IF I COULD!

The final update on AHQ - https://answers.ea.com/t5/Bug-Reports/OPEN-Sims-wear-default-underwear-when-naked/m-p/14318695/highlight/true#M308750

I'm just gonna copypaste most of that with a couple edits:

THIS BUG IS TRIGGERED BY ANY ACTION THAT AUTOMATICALLY CHANGES YOUR OUTFIT BECAUSE THEY BROKE AUTOMATIC OUTFIT SWITCHING!

If you "Change into Nude", you just got bugged.

If you take a shower, you just got bugged.

If you go on a jog and the game switches your outfit, you just got bugged.

If you go for a swim and the game switches your outfit, you just got bugged.

If your one and only neighbor invites you to - what's that thing they say they have tickets for - and the game switches your outfit, you just got bugged.

I assume if you leave for work and the game switches your outfit, you just got bugged!

And if you save the game after any of this happens, you're saving the bug to the save game. Huzzah!

Start a New Game and do any of those actions (including taking a shower or "Changing into Nude") then "Save As", "Exit to Main Menu" and "Resume" and "Change into Nude" and marvel at your buggy underwear.

Like En Sabah Nur said in "X-Men: Apocalypse" when Jean unleashed the Phoenix (before they retconned it and ruined the continuity with Dark Phoenix):

ALL IS REVEALED! 💀

The reason I haven't noticed this at all since 10/22/2024 is because I haven't had a play session where I felt the desire to save the game and resume that save. I've been so busy modding and troubleshooting that even if I played for a bit, I just exited without saving and resumed my "backup" save the next time.

The only good news I have is that switching your outfit manually using the "Outfits..." Pie Menu doesn't bug your game but there is no avoiding or escaping this. The game will automatically switch your outfit eventually, and you'll get bugged. It likely doesn't even need to be YOUR outfit that gets switched. If an NPC switches outfits 'cause of the weather, it might trigger the bug.

If you know a simmer on console, even if EAxis fixes this, their sim's "Bathing" outfit will likely remain bugged with underwear, unless EAxis adds in some code to force reset the outfit, which they can do, but it's unlikely they will.

The question of why this is bugging the Bathing/Nude outfit isn't something I can answer. The bug could be breaking whatever tells the game to equip the "Nude Parts" instead of the "DefaultForBodyType[X]" underwear.

I really need a break now. What the !@#$, EAxis? Seriously. What's next?

──── ⋆⋅⚡ 20 HOURS LATER - <RAGES> WHAT DID EAXIS DO?!

I decided to check my M.A.P. one more time before exiting, and it's not removing when sleeping or swimming on a save that has bugged out, which means "outfit_type_compatibility" commands are breaking with this "bug"!

What on Earth did they do?!

──── ⋆⋅⚡ 20 HOURS LATER - I was wrong! It's not CAS. I was right! It's "EnterBathing" or something related to "EnterBathing".

My immediate confusion upon seeing the changes to CAS was it doesn't explain why "EnterBathing" works properly if you never enter CAS in Live Mode and why entering CAS in Live Mode triggers it.

But it turns out I was mistaken. Entering CAS doesn't trigger it.

Every time the game is officially updated, I delete my old save and create a new one, so I have a new save from 12/04/2024. It's my "backup" save.

I popped into live and used "Change into Nude", then showered, and "Change into Nude" and showered and over and over a few times. It appeared to work properly every time. I didn't enter CAS or leave the lot, then I created a new Save As save game.

Immediately following that, I used "sims.modify_career_outfit_in_cas" and noticed the change to CAS, exited CAS, used it again, exited CAS, then "Change into Nude" and verified that the "bug" was triggered. Then I created another new Save As save game and exited the game.

This was done to verify that saving and loading isn't broken.

SAVING AND LOADING ISN'T BROKEN!

Both of my Save As saves displayed the bug individually after relaunching the game, but my "backup" save "works properly".

CAS ISN'T THE CULPRIT!

If you start a New Game and enter CAS with "sims.modify_career_outfit_in_cas" or via "Change Sim" or "Plan Outfits" then Save As and exit and resume, the first time you use "Change into Nude" it will appear to work fine.

You can even enter CAS, then leave the lot by Visiting or Traveling to another lot, return Home, Save As and exit and resume, and the first time you use "Change into Nude" it will appear to work fine.

"EnterBathing" OR SOMETHING RELATING TO IT HAS TO BE THE CULPRIT!

If you start a New Game and "Change into Nude" it appears to work fine but it's actually not. You just triggered the "bug", and if you save, it's saving the "bug" to the save game.

If you "Change into Nude" or use any interaction that triggers "EnterBathing" and Visit or Travel anywhere and "Change into Nude" again, it appears to work properly, but if you Save As, exit and resume, there's the "bug"!

Entering CAS changes the "game mode" and that's why entering and exiting CAS after doing any "EnterBathing" action makes the "bug" visible.

HOW DO WE FIX THIS?

No idea! 😹

However, I know a few of the things related to "EnterBathing", so I'll take a look, but basically we're back to square one. "EnterBathing" is the command that tells the game to equip your "Bathing/Nude" outfit. It's switching the outfits, so the core function is working prop- no, it's not, because it's not removing my M.A.P. while other outfit-switching commands are removing my M.A.P. EAxis !@#$ed something up badly. The effect this is having on my M.A.P. is proof.

Maybe I can band-aid this another way by forcing all actions that use "EnterBathing" to reset the Bathing outfit before equipping it... I learned how to do this from my work on [EP16] BUGFIX - Costume Box and my WiP Boutique, I just don't know if it will work here.

More troubleshooting required. Later, sometime. I need a break from this nonsense.

──── ⋆⋅⚡ 18 HOURS LATER - They !@#$ed with CAS... and apparently they don't remember they !@#$ed with CAS.

While "checking the saving/loading stuff" I noticed something.

Correct me if I'm wrong, but "sims.modify_career_outfit_in_cas" never gave us a CAS with one "Career" outfit category. It used to give us a regular CAS with the regular outfit categories.

The "Career" category was "hidden" but selected after using the cheat, and if we switched to any of the other categories, we wouldn't be able to get back to the "Career" outfit without exiting CAS and re-entering the cheat. Right?

Tell me I'm not making this !@#$ up! I'm remembering correctly, yes?

If you use WW you'll know about this because WW notifies you when changing the sim's underwear to NOT change the category because WW's custom underwear outfit categories worked the same way when modifying them.

How is whatever they did here affecting "EnterBat- they !@#$ed with the categories! "EnterBathing" is a command (I referred to it as a function before) that switches your current outfit to the "Bathing" outfit category! If they broke the categories then "EnterBathing" wouldn't work properly!

I have no way to verify this yet and the only thing I can ride on is EAxis' track record of being unable to give us new features without breaking old features.

──── ⋆⋅⚡ 17 HOURS LATER - "sims.modify_in_cas"

This was a long shot and as expected it led nowhere. None of the Interactions modified by 10/22/2024 have anything to do with entering CAS.

The command "sims.modify_in_cas" and its variants are not defined in Tuning resources, just like "EnterBathing" isn't defined in Tuning resources, meaning there's no line of Tuning code I can change to alter what these commands do.

If these things aren't in the EXE then they're in resources Sims4Studio can't access or I just haven't found them because there's just so much !@#$ in Game File Cruiser and if it doesn't extract in a readable format then I can't search it for keywords.

I'm pulling up all instances of "sims.modify_in_cas" to rule it out. This requires me searching 200,000+ files for every instance of "sims.modify_in_cas" then reading through all of them. !@#$ this game. 😹

I'm gonna check the saving/loading stuff while I wait for my results.

──── ⋆⋅⚡ 16 HOURS LATER - Just a reminder...

🎙️ A seven-foot frame, rats along his back! When he calls your name it all fades to black! Yeah, he sees your dreams and feasts on your screams! Hey! We don't talk about- I got distracted watching Encanto. 🎙️ He said that all my hair would disappear now look at my head!

I need to check something. You may have missed it when I said it cause it was in a note during my internet blackout, but part of my "Outfits..." PiMP includes a couple custom interactions for entering CAS with the various CAS commands - like changing your Career outfit. I need to pull that .PACKAGE from whatever backup folder it's in and see if the bug is triggering when using a different CAS command.

I still have no idea what's causing this and the more I can't find the culprit is the more I think they broke code in the EXE.

I can't verify the EXE angle as "easily" as I did with the Glasses distortion bug because I didn't catch this when it was first introduced and a lot has changed over the past three updates - so much so that I cannot enter CAS with the old EXE - at least... hmm... there's something else I can try.

I really hope these reports are correct and that this started with Update 10/22/2024 because if they're not, then I'm wasting my time looking at 10/01/2024 when I should be looking at 6/6/2024 since 7/23/2024 broke so much !@#$.

──── ⋆⋅⚡ 13 HOURS LATER (AFTER NAPS):

Here's a link to my AHQ comment sharing my findings up to this point. I've just woken up so I might need to edit it for clarity - https://answers.ea.com/t5/Bug-Reports/OPEN-Sims-wear-default-underwear-when-naked/m-p/14318119/highlight/true#M308713

AS MENTIONED BY PENN IN THE COMMENTS, WE CAN BAND-AID THIS WITH AN UNDERWEAR OVERRIDE. I'LL CREATE ONE AND- <CACKLES> I DIDN'T THINK I'D HAVE TO BE MAKING NUDE MODS RIGHT NOW, AND CERTAINLY NOT AS A BAND-AID TO YET ANOTHER EAXIS !@#$ UP. 😹

The issue isn't the underwear though. I checked every pair of underwear.

As summarized in my reply to Penn, EAxis broke the "EnterBathing" function or something related to the "EnterBathing" function. That's why it's affecting my M.A.P.

I still need to do some more troubleshooting to verify a couple things.

Simmers believe saving and loading is broken. I need to prove it's not so we can rule it out.

Trust me, I know what I'm doing - to an extent - I'm a Rocket Scientist, baby!

I solved the 7/23/2024 Deformer Maps, and I believe I solved the 7/23/2024 Glasses issue too, but they never gave me confirmation that the problem was indeed the EXE even though it was the EXE causing it - but they did fix it shortly after in an update.

If this is EXE, which it might be, then there's nothing I can do because my rocket scientry only extends so far. I do not know how to decompile and recompile EXE files... yet.

──── ⋆⋅🦟 BEWARE THE OOP:

Something is broken somewhere and under certain circumstances - which appear to include simply entering CAS while in Live Mode - it is causing the default underwear to appear on sims when they're supposed to be nude, but it's not only the underwear because it's happening with my [EP08] Mobility Assistance Platform (M.A.P.) too, after entering CAS.

I haven't been able to trigger it yet without first entering CAS but from what I've read, when it breaks, it appears to break for EVERY SIM IN THE GAME as long as the session continues.

It's also possible that if you save after it breaks, you're saving the "bug" too. At least that's the impression I'm getting from the comments in that Bug Report. I'll test this later to verify.

In all the time I've been in Live Mode over the past month, I have not encountered this, until I followed the directions posted by another simmer in order to replicate the "bug". Simply entering CAS once or twice then taking a shower or using the "Change into Nude" interaction... it just breaks the damn game!

ACQUAINT YOURSELF WITH THE "Save As..." BUTTON.

Stop "Save"-ing your game and adopt "Save As..." instead!

Trust me, it'll save you some headache.

ALSO, DON'T TOUCH CAS IN LIVE MODE! [SCRATCH THIS, CAS ISN'T THE CULPRIT]

My M.A.P. is coded in such a way that it's supposed to be automatically removed when bathing, sleeping, and swimming - it's all EAxis code - but when the "bug" triggers it stops removing the M.A.P. when bathing, however, it's still removed when sleeping - I haven't tested swimming yet. This breadcrumb might point me in the right direction, but that right direction might also be a brick wall.

I'll know more after I troubleshoot some more and dig around some more.

☢️ THIS ISN'T MEANT TO BE A RANT, BUT INDULGE ME FOR A MOMENT...

Y'know, our bodies are still broken right? FIVE MONTHS LATER, OUR BODIES ARE STILL BROKEN DESPITE ME HANDING AHQ THE !@#$ING SOLUTION - https://answers.ea.com/t5/Bug-Reports/OPEN-Spine-distortion-on-male-Sims-with-female-frame/td-p/13895791

It's literally one thing after the next - constantly - but I suppose they haven't broken the entire !@#$ing game yet so... mind the gap and just keep swimming, right?
