Citadel bug? In special scenarios - enchanted land
Unless I don't get something, I've faced a bug in the enchanted land Special Scenario.
I've reached level 4 in politics, but wasn't offered to build a citadel. Then I reached level 4 in science, and same thing again. I had 2 cities at the first occurence, and 3 at the second.
Meanwhile the AIs built one each.
I have a screenshot if that helps.
