So, I'm playing as a pirate and trying to take over the universe. I conquer the Tortuga system and marry the Governor's daughter. I am told that the marriage with make the Governor 100% loyal. Well later on in the game that system defected to another faction taking my wife with it. This seems like a bug since that kind of defection is not supposed to be able to happen with that system in particular. So, is this a bug or some kind of wacky game feature?
