ok so here I am on my marathon game......
anyway.
I'm currently using culture starbases to try and swipe star systems from my opponents because I dont want the hassles of battle.
I've stuck 2 culture starbases (maxed out) around the suns of a few star systems deep into opponents space.
I saved the game (a metaverse game) exited, had my dinner, came back reloaded the game to find the opponents planets are in near revolt, one turn later one planet flipped to me before the other planets moved back to normal status.
Obviously my cultral status in those system was not enough to cause the revolt, but because I had just reloaded, the game was slow to recognise this.
this a bug?
