Hello
First of all, my English is not very well
I Played on the Amazonial Map i downloaded it here, I had 40-50 Cities and suddenly der Corruption was very high! On a City that produces 12 Shields, 10 where corrupted and this City was not Far Away from my Capitol maybe 10-12 tiles, before it has a good Production, only 1-2 Shields where Corrupted.
How can i solve the Problem or it is a bug ? I never saw that before!
