@cliffski I reported same bug earlier.

Compass and loading save crash after removing custom country

Compass and saves seems to store info about custom country. So if custom country is removed there should be some sort of failsafe to prevent crash. For compass it could say “removed custom country: “country name”” with blank flag. Attempt at loading custom country save should be prevented - for example save could instead display message, that custom country was removed.
