Civilizations stop growing in population after they make a dozen or more cities.

This doesn't occur on island maps, but I am experiencing it on the new ice berg size. I have found that it only happens when I cover the whole world in forest tiles. Hopefully this makes sense (its kind of hard to explain). So basically just make the whole world a jungle (or other biome) Place a couple different species around, and watch. Each village only grows to about 30 people, as if there isn't enough baby's being produced compared to the people dying. It would be much easier to explain if I could add a screenshot.
