Call for help with Ultimate Collection crashes

I'm not understanding why it crashed. If you installed the mod no witches should show up anywhere. Do you have any custom content in game related to skins or witches? Just asking since you said it crashes when they show up before the mod. The mod should stop them from entering a lot.

ETA: One time I had a piece of custom grass in my game and every time a particular Sim entered the lot at a particular time of every morning the game crashed. Maybe it has nothing to do with witches.
