Ok, Love this game. I seem to have some kind of problem in campaign mode. The enemies are always the same no matter what year is selected. Is this fixable without rebuilding the entire campaign. I can change enemy aircraft in single missions, but not in campaign. How do I get more modern enemy aircraft into the campaign missions for Nato Fighters 5?,also, I stopped playing the North America expansion because I could not take of,f due to Russian fleets spawning on my carrier group. I know this problem is well known, but how do I fix it?
