I was at work playing on 4g internet, I won 3 pvp fights to unlock a pack, the only card that was memorable was gizmo ike, I exited the game through the exit prompts as I had to go back to work. I have done this frequently to collect my 4 hour pack and never had a problem.

Now I get home and connected to wifi to play, it prompts me to update, after I launch the game and go to change my deck I'm missing gizmo ike and possibly other stuff.
