My main save (12 MB) got corrupted (doesn't load). I tried to copy it, copy and change last two numbers, doesn't work. Pls help

I've had this happen a few times. To fix it, all I did was go into Steam, select Astroneer, right click on it and go to Properties. Run the file validation. Then relaunch your game from Steam. Each time I've done it this way I was able to load the save file and not crash.
