[thelegendarystupid]

Okay so the thing is, I dont know when is started but I tried to have sex with the draugr, all the animations worked fine before and I havent added anything new so anyway, the first scene work 100% fine, but if I decide to choose another scene, this happens:

sorry for the inventory in the front but we can see the character is not allign... and worse, I can freely move while the npc stay locked in the loop unless I stagger him somehow.
