Sooo ran into an incident where my colonists were sieged, decided it'd be a easy fight with a ton of melee pirates; However, turns out the geneva convention doesn't exist on a rimworld, and they immediately toxic gassed them all.

What proceeded was a immediate kidnapping of as many people as they could, leaving the rest to choke and die, and now I'm stuck with a contract where the pirates won't start a new contract.

Since there is no indication that this is a feature, is there any fix or work around?
