Not really related, but simply strange: In my campaign, the Seleukids have reduced the Bactrians to a single settlement. Bactria is still shown as being super rich on the graph, with over 3 million mnai and still rising...is that the money script at work?
All the remaining empires in my game are insanely rich, ie multimillionaires. Even the Casse who have about 8 full stacks just sitting around the British Isles as they have nowhere left to go to :P
