jimkehn - have you tried reopening the turn in Dominions and re-ending it? This problem's pretty rare, I think probably the file is actually genuinely corrupted.
Sorry to be so slow answering. Trying to get started harvesting wheat. But to answer your question Llama, yes I did go back into it and try re-ending the game as posted in my original message. If you have an email address, I can try zipping it and mailing it to you via an email address. I know this has worked before in games that were not Dominions.
The game is so much more fun when there are fewer players who do their turns. I hate it when you get 20 players, cuz there is always SOMEONE who can't or won't do their turn. Just a word of appreciation for all of you for being prompt.
