I am playing on my computer- Windows.
I save my colony and then close the window and go to bed, the next day all of my progress is GONE.
It has done this to me twice now.... Anybody know what to do about this and how to correct it?
I am very sad because I was very proud of my colony and now it is gone. :(
If you are logged into Facebook via the game, logout. There are issues with Facebook syncing. Make sure to make manual backups of your colony.
