Is this a bug or a feature?

[armovir2009]

Bug\feature: I've just mentioned, that my wealthy prisoners (lords) can auto-bargain themselves out of imprisonment.
How to Reproduce: Last time I'v captured the "king" from Vlandia and he just presented me 3 towns aoutomaticly whithout my permission and vanished from the party. At that moment I have all the branches of trade and charm to the top.
Comment: if it's a feature it is funny, but what if I want to imprison them as long as possible (want to save Sturgians, feeling sad for my slovenian brothers being victims of snowballing ....... )

+1 I've experienced this as well. I get a message that says barter accepted with no interaction or say from me. This is one heck of a fubared feature.
