I was really really enjoying this game, and I find 9/10 games on iOS shit until I tried to play this morning and all of my progress was gone. I didn't know if it was a bug or if that was the way the game was supposed to be played but I see now I am not the only one. I didn't switch devices or do anything out of the ordinary. The only thing I can confirm is that I did get a message that my ipad storage was getting full. I had about 200-300mbs left in case that is somehow related. Really want to keep playing but would hate to lose my progress again so I might just wait for the update to hit.
