Hm Thats quite unfortiunate. But I dont think I wanna change my custom Map up for that. I had a good game on it even if I didnt triggerd Cilma Change and I dont think our Civs work simmular? Strage indeed tho.

1: Flooding does not show up. I know that may be a common thing across custom maps. The description says it will form an archipelago, but it does not. The tile can be submerged but still looks like a regular tile, as if nothing had happened. They're not able to be traversed by naval units, so whats the point?
2: After flooding hits, all cities (even if you have flood barriers) begin to lose tonnes of amenities. My capital had around -80 amenities! despite being protected by a flood barrier. This caused all cities to stop producing anything, my economy tanked and i could no longer do anything, again, this is even with flood barriers in all cities, including inland ones.
3: Immediately after flooding starts, AI cities start to rebel and you end up with a chain reaction that essentially means that they are flipping constantly. Again, I wouldn't mind that if it were happening within the game system, but because of the broken for some reason amenities issue, it is unstoppable.

Wow.. nice mod. I think it would be more nice if you add Mt.Erebus also.
