Thanks mate.
I tried a few different things, and I couldn't get a re-region to work for anything. The datapads, difficulty, or survivors wouldn't pop. My game kept changing the difficulty to "Custom" after a save point, and all datapads are collected, but it says only 96% completed. Only the one for finishing the game popped. There's something different about these saves, maybe Save Wizard will fix that at some point.
Thanks again for uploading it so I could give it a try. I'm just going to have to slug it out this weekend.
