Well, snapshot says it all. I invade the continent, destroy enemy cities, found two cities and...get pollution twice.
I think the reason is the following weird one. The upper city only exists for 4 rounds and I have used 4 leaders (hundreds of battles when I landed there) in 4 turns to create airport, barracks, factory and offshore platform. Plus an offshore platform in the southern one. Does pollution work that way? The game "imagines" that 240 shields were used for a factory? Is it the same when you rush production?
