I'm playing my first Sunset Invasion game and have noticed that the Aztec Empire has appeared in Mali, upon closer investigation it seems that despite the Aztecs having never arrived or in fact ever had any events fire that foretell their coming or arrival the Sultan of Mali has somehow usurped their title as he is not Aztec and none of his family are Aztec yet he is the Aztec Emperor. Is this a bug and if not how did an isolated Sultan of Mali get his hands on a title that has no representation anywhere in Europe or Africa?
