Yes, but i replaced the skeleton anyway and disabled the plugin to test it.

Are you also using Realistic Ragdolls and Forces?

Check frame rate. If it is beyond 60FPS or 60GHz monitor refresh rate then it could whack your game your physics. 

After trying \[this mod\]([https://www.nexusmods.com/skyrim/mods/93156](https://www.nexusmods.com/skyrim/mods/93156)) i found that the hanged people added by this mod just fall to the ground in my game whenever i encounter them. My game is working fine in every other respect. I first supected XPMSE to be the reason, but the same behaviour also happens when using the vanilla skeleton. It's not caused by a plugin either (tried it with all plugins disabled). Anyone have an idea what's causing this?
