Now it just freezes everytime I touch any FavCat related button in my avatar menu. Sometimes just clicking "avatars" freezes the game.
After the freeze I can still hear the game audio, people talking, the game just never starts back. I kept the game running overnight listening to radio static to help me sleep and it was still frozen.

Edit: Fixed. it was being stopped by BundleBouncer.
