This just happened to me, except I added a winter league in the middle of a season. Now, my game gets to 100% loaded and just hangs. I can load a different league and it's fine, but I think I may have corrupted my 7 year history league. Any suggestions on how to fix?
Edit...My league loaded. It just took a really long time the next time I tried. I only lost 3 days of games since my previous save. Whew!!
