I'm in big trouble.
I fininshed my 266 turn in my current game, I click "End turn", and all the 20 AIs did their turns, but when it got back to me for my 267 turn, I got an error message that says "Integer overflow". Whether I click ok or not, I can't continue playing.
Every time I reload, the same happens again.

Any idea what may be wrong?
Thanks.
