Multiple race instances
I'm not sure if this is exclusively an IotA issue, but I've only seen it with the Ancient races. Sometimes there will be more than one instance of an Ancient race on the map. I'm guessing that the game just doesn't check to see if they already exist before creating them.
Is this intended? If so, we REALLY need a way to tell them apart - it's a royal pain in the rear when there are two Hezog at war with each other, and you have a Drox Guild quest to make one of them the most powerful race in the sector, and no way to tell WHICH Hezog they want you to help....
