Ok so I am playing Byzantium and wanted to try something different so I decided to move my capital to the new world by conquering some Mayan land and waited for the ottomans to take my European holdings to force my capital to move to the new world. It is now 1608 and I have come back to Europe and reconquered all of my Greek land and Western Anatolia and want to move my capital back. I moved my capital next to an English colony and sold them all the land around it so my capital would be isolated yet it says I can't move because it is still surrounded by a big heartland. What gives?
