I'm also having the same problem. Even when I deactivate all of my mods the bug is still occurring. I am also using FNIS but Idk if this happens with vanilla. **Found The Solution Delete the following Data/Meshes/actors/character/characters/defaultmale.hkx Data/Meshes/actors/character/characters female/defaultfemale.hkx This worked for me but the only thing I tested it with was the float up section in tel myrnth. Not sure if it solves all of the problems but I would assume it does.
