Crashed and lost expansion.
Hello. I was just playing and I went to my Mine. I had 1 bomb to enter the mine. I found 2 ruins, money (I can't recall how much) and 500 food. So it gave the option to expand. I clicked it and went back to the forest clicked the area I wanted expanded and clicked the button to start expansion. (I had plenty of coin for the cost).
Then my game crashed. When I got back on, it seems nothing saved. The expansion wasn't open, the food I won was gone. I went back into the mine thinking I would start that over since everything went back. Except I didn't have the bomb to go mining. So... The game ate my bomb and subsequently everything I had gained.
