Ok, I've got my civilisations set up (Germany, France, Italy, US, UK, USSR, Spain). There's also a minor nation, the UN. When I load up the game, it loads these civs, then creates two more, which are duplicates of two of the others. Help?

If there are more AI slots than civilizations you get duplicates.
The only problem ingame is to tell them apart in diplomacy.
Make less AI slots in a custom game, or a smaller map.

It happens when I don't do it custom. How can I regulate how many AI I want?
