I came to the forums asking for help both in finding it and in getting it back.
I used my iPod 4g, which I still have and still shows all my era achievements on game center. But the progress itself is gone. I still use the same apple account. I could check my purchase history, and there would be lots of gralat packs from 2011-12.
I was just hoping they had a log of some sort so they could see that one of them went to my IP address.
