We NEED an anti-corruption file saving.

[Bederatzi_Dokuz]

It is my second world that is corrupted and there is no publicly known way to fix it.

Since my first world was corrupted I started making backup copies every 50 days of play for fear of losing one of my most important worlds again and it just so happens that the moment I stopped making backup copies my world newest and most important ended up corrupted.

I'm not a programmer and I don't know anything about save files, but I imagine that it is not impossible to make an option that allows the world to be saved 2 times alternately where if the current save file is corrupted you have a save from the last time that you closed the game.

I don't know if you understand what I'm saying but it's this:

Add an option to the world configuration a Local Backup
When the world is generated it will generate Backup 1 and Backup 2
When the world is open, it is saved in one of the Backups.
When the world closes and reopens, it takes the information from the most updated Backup and begins saving the data in the secondary Backup and alternates between where the world's data is saved.
If the world becomes corrupted you have the option to start the world in the secondary backup where the world data is corrupted.

This would make the worlds heavier but is a better option than having no world.

Could your world be saved via the Rollback option? DST already keeps a few backups in the Rollback menu, you might be able to restore to a non-corrupt copy of your world. I've encountered both situations where rollback was able to reverse corruption, and was not. It's worth a shot. When I was an active DST player, I kept a rolling series of backups, and updated, making a new copy and deleting the oldest copy, every time I finished a play session.
