Don, you should switch to decaf. As you said, it's a small thing. Indeed it is smaller than that. The 12 scenario error has nothing to do with statistics, it is actually from the game description, which doesn't factor into anything.
Anyway, I've fixed it. Don't know where the 12 came from, but it was never a factor in obtaining the campaign ribbon. In point of accuracy, this particular issue has nothing to do with Vassal, it should have been posted in
General Discussion. Better yet would be to inform us under
Errors & Omissions.
