The first nation I started out as was Carthage. On both that game and every one since (including seven other nations so far) between 5 and 20 seconds after the game starts, it goes to the loading screen and shows some nation other than what I'm playing (the exact one varies) and then loads to a game as Carthage with the UI gone. I'm at a complete loss and have tried a couple clean installs. I'm using the steam version and every other aspect of the game appears to be functioning.
