How to win an offline tournament!

I noticed one issue. The starting save file could change when transferred from one computer to another (and launched in a different game). I encountered this a couple of times, and before that, I checked it with Prospector, so I knew what should be in it. I don't know if the HD mod could have affected it, but it's unlikely. I didn't analyze what else could have influenced it. The first case seems to have been with some starting save file taken from HW, and the second was with a starting save file from a campaign scenario that I recently localized.
