I can't seem to detach a collar. It seems to work if I relog, but after wearing it for a while, it refuses to detach. I can switch outfits and teleport out of sims and it still won't go away. I've tried stopping animations, clicking detach from the inventory menu, and clicking detach on the item itself. So far, relogging seems to be the only temporary solution. How can I remove this item without having to relog every time I want to take it off?
