I had captured a Drengin planet and had 5 ships in orbit to repair and protect the planet from being recaptured. I advance a couple of turns watching the area and when a nearby planet to the one I captured spawns a shipyard, the planet I own just automatically turns back to their control. No transport was sent, no battle engaged my orbiting ships, I just lost the planet without any actions on their part... Now I don't think influence has been introduced yet where we can just flip planet's allegiance purely because of cultural influence, has it? If so, that makes sense as it's still an area under their control but I hadn't seen that in my previous two games and this is with the Opt-in beta. Anyone else see this?
