In my new conquering ways, I've noticed that sometimes if you're attacking an AI civ, they can pop out a new unit in their cities during your turn, presumably through slavery. Of course as they're unfortified and unpromoted at that point, they're usually simply more experience points, but this seems like a pretty naughty cheat to me. It was one of the only genuine AI cheats in Civ 3, and I don't think I've noticed it before Warlords, so is the ability for the AI to rush out a new unit in the player's turn a new feature?
