I have tried disabling it and using HD Werewolf Retexture instead which has no skeleton file and have the same issue. I have a mode called Underworld Werewolf which does have a skeleton file, no plugins, and it is lower priority than XP32. I am NOT using SOS nor Everybody's Different.
So I just went on the mission with Farkas and my game is stable, no CTDs, and the only issue I am running into is when Farkas turns into a werewolf when I get trapped, the werewolf model is invisible.
