I got this weird noise that has been going on for a while now. Its like a turning on noise. It happens when I hop on or hop out of a power armor, it happens whenever I load a save. It only happens with one character. It's not because of a mod, I uninstalled every mod I had just to make sure so it's something from the game. I already checked if it was the gauss rifle, the gamma gun or the musket noises, they weren't. I have a recording of the noise here Any suggestions?

So I´ve encountered a strange glitch as of late. Sometimes when any npc enemy, be it humanoid or creature gets ragdolled by unrelenting force or any similiar and dies while it it´s trying to get back up it will die, ragdoll for a second and then get stuck on a t-pose dead. While on the tpose it will be completely unresponsive ,exept for attacks it will not move or do anything. Strangely enough it happens almost guaranteed on cows and deers, sometimes on giants and (fortunetly) almost never on humanoids. Quicksaving/loading or disable/enable seems to make the corpses responsive again. I found this mod out by accident while playing as a werewolf- I thought it was a random visual glitch but then I killed as bunch of cows with power attacks and noticed how most of them got stuck and one was sent away flying upwards. I haven´t ecountered it with bears, sabre cats, mudcrabs or spiders, neither with dragons or mamooths since they can´t be ragdolled anyway. I think it may be the FNIS new idles fault. I don´t remember encountering this glitch on my previous playthroughs without FNIS and it´s only in this playthrough that I´ve been using some animation mods. I really have no clue what may be the cause of the glitch, it isn´t terrible as F5 F9 can recover the corpses and there aren´t that many cows in the game anyway. My load order Includes XP32 maximum skeleton, FNIS users and FNIS creatures. I´m playing at Ultra High
