I always had a problem with them mannequins, either they ate all my armor, moved around the house, or they started speaking. but recently they stopped equipping the stuff i give them. they equip it when i give it to them, but after a reload and entering the house, they are no longer wearing it. its still in their inventory though. Also these are the vanilla mannequins from the original game, not my creation.

I recently installed the unofficial skyrim patch, but removed it. cause i didn't like the new daggers sheathing sounds the author added. i got the problem around that time, could it be related?
