Thanks to double tag, I had two packs to open. After the first one opened and was on the screen, I decided I wanted a different boss blind and hit the reroll. This caused the second pack to open, overlayed over the first. When I picked my cards from the second pack, it immediately crashed my game and upon relaunching the game, I was stuck on the card picking screen with no cards to pick from.
In case it's relevant, the pack was the mega standard cards pack.

the crash is interesting, might've happened to others but no examples come to mind. As for the pack being bugged, that always happens when you reload a double tag pack.
