It's a large list! I may not need to beg your indulgence, though... I seem to be making progress. I think I've identified one of the bad actors (pun intended): Bijin Wives/Warmaidens/NPCs/AIO. When I disable those, all is less not-well with the world. I'm confused as to why that matters, because the first thing I did was to replace the body, feet, and hands NIFs with my custom body type, and that alone didn't stop the CTDs. Only eliminating the mod(s) entirely seems to stop the CTDs, so now I need to find out what else I've missed in those packages that could be causing the problem. I don't think textures could cause it, so I'm guessing it must be an issue with the ESP file (only one when the AIO package is used). What else is it conflicting with? I've also been suspicious of the QUASIPC patches involving it, but eliminating QUASIPC (it's getting obsolete) alone also didn't stop the CTDs. I used to use Bijin but now i use Botox instead
