Crash destroyed savegame
 

After a crash the save does not show up in the game anymore.

1. I created a league.
2. Saved it.
3. Made a backup.
4. Simmed for 4 years.
5. Restored from Backup named "Historical 1901 Restored".
6. Loaded that restored save.
7. Simmed for 4 years.
8. Game crash - Save does not show up in the game anymore. The folder exists and I manually deleted it to create a same name savegame.

However, if this would have been an important save I would not have been able to reload the game anymore.
