I left my game running and when I came back all the puzzles that i have accomplished have been erased. The well that I found underneath the rocks is covered again. My lab is back in ruins I had to send an adept scientist to recover the different pieces. My food count and my tech points were not lost at all. I think there is a glitch in the game as every upgrade I have made is still there when i click on the Tech button. Can anyone tell me what the problem could or might be????
