Yeah I have. It happens every season or so. What you could do is go to "Load Game" (not "Load Last Game"), and there you will have your saved games there, as usual, but this time you will have, in addition, another game. The game name will be your original save game name, but this time with a "(Backup)". If this happens repeatedly, everytime it will have another "(Backup)" to the original backup. For example, "***" is your original game. It cannot load and now you will have an "*** (Backup)". If it happens again you will not have "*** (Backup) (Backup)", but an "*** (Backup)-2", which will be followed by "*** (Backup)-2 (Backup)" and so on, adding "-2"s and "(Backup)"s.
