If someone can shed any light on this I'd be grateful. edit: save attached in this post. In the game I am playing at the moment, there were four AI remaining: the Romans, the Sumerians, the Indians and the Greeks. I was at war with the Romans and at peace with everyone else, none of the AI had contacts with anyone but me. I destroyed the Romans, razing their last city. The Indians and Greeks were polite, the Sumerains cautious. I was busy repositioning some towns and I noticed that after abandoning some towns (including an Arabic one and a Byzantine one) the Sumerians had become furious (the Greeks and Indians were still polite). I'm pretty sure the Sumerians never met anyone, so why did this happen...any ideas?
