I am not surprised. The .bsas seem to work for most people. I don't know why they always CTD on me. I guess I am going to have to always unpack them and either add them as loose files, or create omods from them.
I just uploaded Animal Friend, which makes regular animals like wolves, bears, sabre cats, etc... friendly to the player. It can be found
here. It is really the complement of Nature Summoning, as the two will let you play a witch/druid type character, who is a friend and protector of the animals.
