I've been having issue with saved data errors. On the Game DMG, I saved a few decks, which is when I first noticed it. When I relogged onto the game, I noticed all the changes I made had been discarded, and everything was the same as before I made the changes. I've been having this issue for the past few days, if anyone could possibly give me an explanation of what's going on.
