Played as Bulgaria capitulated twice. First time the ottomans got into Burgas which instantly lost me the war. Second time without a single troop entering my territory. Germany annexed me and the game ended. I would really like this to be fixed soon.


my game crashes in some point in july 1939, when im playing as the ottoman empire or any country, also soviet republic of transcaucasia switches to the normal soviet focus after 1939 something?
