my progress was lost with a recent update. i was taken back to the beginning of the game. i had been playing for some 5 years. support said they could not find my progress by my email but if i sent in proof of purchases made in game they could look into the matter. In other words, prove you've paid to play this free game or you're back to the beginning. I did make in app purchases, but will not be providing proof nor playing any Pixel Federation games in the future.
