Just finished turn 232 of my v139.2 game, and it seems that some of the AI civs are getting an awful lot of culture, especially Polynesia. My focus was primarily on science and building military units, as I was engaged in constant warfare as China against Rome & Japan. However, I did also keep building culture buildings whenever possible. Well, I've successfully completed four trees of cultural advancement so far, but although the Polynesians show they've completed only three trees, I think they are actually almost ready to build the Utopia project. (This info was gleaned from those periodic pop-up comparisons of cultural advancement of all civs, and the Polynesians are WAY ahead of everyone else.) Am currently allied with Polynesia, so sailed a ship around their terrritory to get a clue on why they were so far ahead culturally. Well, according to what I can see, they have not built ANY Moai heads on their coastal hexes. This seems rather strange: Are the Moai heads really there, but simply not visible for some reason? Or, are the Polynesians the surprise beneficiary of a random hex that produces bonus culture instead of the random 210 bonus gold that has been separately reported?
