Sorry I should have given more details. 1. I started a new game at work today at about 12:30. This was not a new world. 2. I played until about 13:10. I quit the game right after night, after it said it saved. 3. Closed the game. Waited for the Steam sync, then I closed Steam. 4. Played AGAIN at work at 16:30 until 17:00. At that point, I was able to continue my game. 5. Closed the game. Waited for the Steam sync, then I closed Steam, like I did after lunch. 6. 19:00: Logged into steam at home, waited a little bit for that cloud sync, then I started the game. There was no option to continue. I started a new game and I still had research points and unlocked stuff but verything else was gone. 7. Closed the game and logged on my work computer from a distance using VNC. I went to the save folder and it was empty. Steam has NOT been started on the work computer since the time I logged at home. It seems the save was already gone before I went home, unless I'm looking in the wrong folder. Hope that helps!
