So the map was fun, but there are still a few connections to work out, Urgench the circle is either out of place or not connecting correctly, because it looks like it should connect to Khwarezmia, but does not, and connects to Khorasan when the circle is not even close to it. Also Samarkand looks as if it should connect to Fergana Karakhanid but does not. I thought that the eastern bonuses to be outrageous but if you were trying to balance it with the west I understand
Great map. Unfortunately, the bold border lines can make deciphering connections a bit difficult. Beware also the relative imbalance of various superbonuses (not that that's a problem - just a reflection of history).
There were a couple broken connections. The only one I recall off the top of my head was Thessaloniki to Bulgaria.
