BUG: Save game gone

[Rockinsince87]

I would suggest very robust save game strategy:
1. When the game starts, it creates a temporary backup of the save, and only then attempting to load the game.
2. If the game confirms that the save is operable, it moves temporary backup to the permanent one.
3. If the game fails to load the save/crashes/whatever, the next start will detect the backup and will be able to at least notify the user that the last start was unsuccessful.

+1, that'd be really good

Yep this is exactly what is needed.
