I'm unsure why this is happening, but every time I try popping up the werewolf tree my game crashes. Is it because the amount of mods I'm using (Nothing related to the werewolves I mind you) or is there a certain update/patch that I'm missing?

May I also remind you I'm using this game from off of Steam.

Can you post mod list/load order?That would help alot. It could be conflicting mods (you'd be surprised what might affect it)

I suppose. Here's my list:
