I may have found a small bug:
If you buy slaves and they join you and you keep the shackles on them for... roleplaying purposes
Everytime you load your game, you get the "Hotlongs is enslaved" message for each and everyone of them. Would be ok, because they are, after all
Also, everytime you load your game, they are assigned the "obedient slave" job.
Don't know if that's intented behaviour of the game or a bug, but it's rather tedious waiting for all the messages to display and to remove all the jobs, every time you load a game.
