I've had Astroneer for around a month, and have played around 20 hours on the same saved game. After I updated to the most recent update, it still ran fine, but after saving my world and logging off the second time after the update, I came back and my save file had been reduced to the size of 1 KB and I could not load it, rename it, duplicate it, or generally interact with it. I've made other save files since then and none of them have had any issues similar to this. I did not close the game prematurely before saving, I'm certain of that. I'd like to know if there's any way for me to fix my world and gain my 20 or so hours of progress back. I've restarted the game, uninstalled and reinstalled, scanned and repaired files, and restarted my computer multiple times. Any suggestions or fixes would be greatly appreciated.
