This is soooo strange, we have a sorcerer going to the armor displays, however only one of them can be disabled from thrall use???
This is how people are losing thralls, due to these random wierd bugs where you cannot control living settlements even tho you are supposed to.
We disabled all benches/placeables, locked ALL doors made sure they basically cant move, but then we have this happening, luckily nothing happend in this instance, but i am not surpriced how people are missing thralls then, i made a video of it and reported the issue to the right channels.
