[0.98.38] Slavemongers stealing prisoners

[Lallering]

I don't know if it is a game mechanic or what, but it's too annoying that i have prisoners on the hub and then slavemongers come to my house and break the door to enslave my prisoners like nothing, they don't have to pick lock the cage or anything, and then when i kill all the slavemongers and i put the prisoner again in the cage, now it's bug because he is now my ally and I do not know why it escapes from the cage like nothing without pick locking the cage or something, he just appear outside of the cage when he recovers.

Sorry if my english is not too good.
