I've just run into this problem as well. Is there is a way to simply abandon the game? I can't play the single player 4-player Oceania anymore, because it simply sits there forever.
I'd hope so. This is one of the three major issues I've encountered repeatedly. The other two are the 999997 sequence of dice rolling and losing track of players at the start of the game.
Of course the losing track of players at the start and what you've run into during the course of the game could be the same bug.
Here's hoping the admins can enlighten us.
