In my current game, Italy had conquered Tunisia. The US took all Tunisian ports, and was asked if it wanted to liberate Tunisia. I said yes. Then I was asked if I wanted to revert Tunisia to the French. Frankly, the answer is no, but in game terms, one should, so I said yes. Then MWiF asked if I wanted "Return territory to Tunisia (United States)." I said yes. However, the US still owns a bunch of hexes in Tunisia. Should they?
Here is a picture; the next post is a saved game from the liberation step, where the problem occurred. Also, I had focus problems with the saved game (although not when I first played it); the dialog box wanted to stay behind the display screen, and it took some contortions to get it in front.

I thought I knew how to play this game....
