Alright, I've discovered ONE of the issues.

I had made those custom tattoo's for Raven a month or so ago, and when doing that, I didn't save them as the right file types. So when Daz was trying to load specular maps, it was trying to load massive color PNG's, so that was causing crashing...

Now this is only on Raven... I still have no fucking clue why the other characters cause crashing. But I'll get there. At least I've figured out Ravens glaring problem. And I'm currently fixing it. I've remade all the textures. I'm now replacing them in all the places they go... There are like 50 places. So, once she's all restored with the new textures, I'll test her and hopefully, she'll be good to go and I can move on to the next problem.

Overall this is good news. One problem down.
