Prisoner Collar bug

[Mythic]

(Pre-note. This did not happen to me, but another)

Said person had a Prisoner collar which was un-named, And was taken to a Slavemaster NPC.

Upon speaking to it, the character lost the prisoner collar item and was made into a Slave-Collar

Is this meant to happen automatically? Because it feels like it's a bug. As it should be a conversation to cause that? not something that is automatic?

This happened pre-EE too.

DM had to remove it IG.

So as far as I know it's a known issue. Just have to not talk to the slavemaster when in a prisoner collar. I didn't think prisoner collars had names but its been a while since I had one of those.
