Better Exceptions - Real-Time Exception Alerts Public Release
DOWNLOAD REMOVED AS THIS IS AN OLD VERSION. FIND THE LATEST RELEASES AT TWISTEDMEXI.COM
Better Exceptions expands on the LastException functionality, providing in game alerts the moment an exception occurs.
This will help players identify what in-game event actually caused an error. It will also show players the most relevant parts of the error to assist with identifying the actual issue.
Prompts will give you multiple options, including automatically opening a full report with extra diagnostic information and opening the raw exception file.
Even better, now if there is a known issue plaguing the current version of the game, Better Exceptions will check and alert you. In these cases, it will link you the AHQ article related to the issue. You'll also be given the option to ignore the exception until a patch is made available, though I don't recommend this until you confirm it is a problem that will need a patch to be fixed.
Clicking "View Issue on Answers HQ" will bring up the article with information from others explaining the problem. If it matches your issue, please click "Me Too" on the post to show that this issue is common and needs resolved.
Due to the large variety of LastExceptions, I expect this mod will improve with time as I receive feedback from everyone who uses it.
I welcome any LastException reports from this mod to be posted in my Discord:

Thanks everyone :)
How to install:
This is a script mod so make sure script mods are enabled in your game options. Download the .ts4script file directly to your mods folder. Do not open or unzip.

can you help me identify what this error message means Exception Summary Exception Date: 2026-03-31 19:18:42 Game Version: 1.122.218.1030-1.200.000.699.Release Category ID: part.py:268 Recommended Action No mods were listed in the exception but you do have mods installed. Close your game, try removing handfuls of mods from your Mods folder and retry what you did when you received the exception. If the exception does not occur then the problem is likely with that mod. Check the mod download for any recent updates.

No nevermind. I see what I did. Thank you.
No problem :)
Maybe another mod I have is conflicting?
Possibly but unlikely. If you check you're last exception file does it have an error or just 3 short lines like xml and root.
I put it directly in the mods folder
I'm not sure what i did wrong, but the mod is not giving me notifications
Script mods must be on in your gameplay options, it's separate from just regular mods. You should have a single .ts4script file in your Moda folder. Don't open or unzip it. It can't be in a subfolder
Discord link is still returning invalid / expired.
Thanks. I'll fix it when I get home
Hi, I click the link to the discord and I get in "invalid" response from the site :(
Fixed it, try again please :)
