I had a lot of CTD issues when entering Fort Dawnguard at first but after working through many mods I narrowed it down and reloaded some of the other mods that did not seem to be a problem. Now though I sometimes see an enemy with their arms out stiff and naked. If they are human they are also headless. I have seen this with Trolls and Bears and some Bandits. It is not always and it is quite infrequent and after you kill the enemy you cannot loot the corpse. The corpse is just standing there and you cannot interact with it anymore.
Has anyone else experienced this? I am trying to figure out whether it is some game bug or some mod is causing this strange issue. Thanks in advance for any reply as to whether you have seen this happen or not.
Edit: I went into the mod manager and unchecked all the mods. I loaded up a save and went to an area with enemies that I can see this happen. Even with all the mods unchecked I still get the stiff, naked, headless enemies. They speak and will chase you but, it is pretty strange.
