If not, Ill start the process of testing each mod individually to narrow it down. Figured Id ask first.
What mods are you using and the load order?
I might be willing to help test it out.
Did any of them mention anything about wolves.
It might also be one of the other Arthmoors mods as well since he might have put some of those fixes in them .
It is a known issue with animations in the Unofficial patch and a fix will be included in the next update (no I don't know when).
