I just lost my save of around 20 hours to a power outage that happened the instant I saved :(. Even the settings are gone

It would be really great if the game kept the last couple of saves backed up to use in case it can't read the main file. Just so that no one experiences the same thing

you heard of turning autosaving to save every 5 mins insted of 10?

There's still only the one save file. That would not help
