Wish I had a screenshot (playing with a Mac keyboard but on a Windows boot camp instance - no print screen button) but a couple of times I have been gifted a Khan from a CS as a Civ other than Mongolia. This is a known and rather common occurrence. What is funny is that one of the Khan names is Genghis Khan. So you can wind up with Genghis Khan bravely leading your forces into battle with...Genghis Khan. Anyone else had this one?
