I hold an adventurer from my own realm in my dungeon. I have the 'ban' option available. Having tried it 3 times, it tells me each time that the ban is placed and the prisoners released at the gates
However he is still in my dungeon, is not on the banned list, and is still in the realms character list marked as in prison (not return)
I thought this action would be instant. Is it a bug, or will it apply at turn-change?
