Hi, I'm playing as Winston Churchill of the English Empire, single player, and I can't make a colony out of the cities I have on another continent.
When I open the "liberate cities interface", I get the option the grant independence to x, x, x cities (all I have on that continent), but when I click on it, the interface disappears and nothing happens... I've tried many times, restarting the game etc. I've also made a colony in another game with the same version (302), but that was in multiplayer.
