I think I've discovered a really odd bug with cloaks, perhaps someone can try it out and see it they can get it to happen on their install.

If I behead an NPC, then loot their corpse, taking the cloak, then leave the cell and come back, the game will crash trying to reload the cell. If I repeat literally every step except the part where I take the cloak (i.e. I loot whatever else and leave the cloak), I don't get a crash.

Once the cell resets, I can return there without issue, even if I loot the cloak from the beheaded NPC.

This is with Cloaks of Skyrim, and Wet and Cold. I also use Frostfall, but I'm not sure if the same issue would happen there. I've also only seen it happen twice, once with a Thalmor and once with a Forsworn (so also only tested faction-added cloaks). I'd bet it doesn't matter though, since they all use the same item slot, which I'm thinking is bugged somehow.

Certainly one of the weirder bugs I've heard of. It would be good to know if it's just something messed up with my install, like some weird mod conflict that I'm never going to figure out, or if it happens to everyone with a cloak mod, or what.
