A friend and I were having a great time playing a co-op game as Italy, when we noticed that he was showing something like 100 for the stockpile of oil and I was showing closer to 6000. The same thing applied to the energy levels (though the numbers were different). As I was the host, I saved the game and we reloaded. It was then showing the same numbers, so I guess it was some lag problem and/or something to do with the fact that both of us were entering trade agreements, etc. Has anyone else experienced this problem?
