How can I move my capital? What requirements have to be met to move it?
I am playing as Ryukyu and would like to move my capital from Okinawa to Australia. The first time I tried, the mouseover tooltip said I need 200 ADM points. Got there and it was still grayed out and the tooltip now said that my capital needs to be isolated. I'm on an island surrounded by the Japan, Ming, and Korea (although I have colonies in Taiwan and the Philippines). What can be more isolated that that?
The tooltip is outdated I believe.
You can only move your capital to another continent, if you have only one province on your current continent: i.e. just the capital itself.
Australia is a different continent to Asia, so that's why. I'm not sure if China counts as a different continent to Japan/Ryuyku, possibly not, so it's possible you could move it into the Asian mainland, but not to Australia, Europe, Americas etc, unless you just have one province left where you are now.
