I'm playing a single player P&N game, and something's really bugging me... I've conquered this Sergetti planet, but no matter how long I wait after putting 200 troops on it, the planet doesn't stop rioting... The battle for the planet was quite long, so I suppose that caused a lot of unhappiness, but I'm now at almost 2425.0 and the planet is still rioting... another planet in the same system I conquered soon after is stable at angry... this is weird!
