This is a very very minor details, but as it stands right now it doesn't handle non-contiguous or ring duchies very well. The duchy names for "Margraviate of Tower Fatmilak" and "Candiels" and those for "Donghaiwei" and "the First Temple" overlap on the Dwilight map for example.
But, as I said, it's an extremely minor point which shouldn't overshadow how cool this map is!
