We released a minor patch 0.4.11 that fixes the way the game determines the next territory to unlock. Players complained about the bug that caused the next territory being the one that's already unlocked before.
How about joining our Discord server? Different game tactics are discussed there, and sometimes you can directly chat with the developers :)
