I just discovered that I had all my gameplanning settings erased and reset to default for one of my teams. This occurred randomly and for no reason. Has anyone else experienced something similar?

Did you change coaches?

No.

The AI will reset your gameplan only if you go into a game without enough plays selected, or have too many plays selected/scout plays selected

I had 40 offensive and 30 defensive plays selected, that I am 100% sure of. I could have possibly scouted too many plays accidentally, but I doubt it. Also, I can't imagine this would change every aspect of gameplanning. My entire Misc page, in fact everything in gameplanning except rules, was reset to default.
