I've been playing my first game on Regent level, as Egypt. I've been at war with Japan, and have had most of the world in a military alliance with me against Japan. When the Greeks finally destroyed the last Japanese unit, quite a few of my cities went into civil disorder, and I can't figure out why, because when I cycle through the city displays, they are mostly full of happy people. In the Civilopedia it only says that civil disorder arises when there are more unhappy people, and I don't have any unhappy people. What's going on? Will they just straighten themselves out if I finish the turn?
