When opening a booster pack (the image shows several because I'm gold sticker farming on anaglyph), you still have the option to select to reroll the boss blind (I did so, the boss was a wall and i was going to lose to it.) After clicking reroll the game opens another booster pack causing 2 sets of packs to overlap. The first image was taken after I selected a joker and there appears to be 5 jokers selectable. After selecting a second joker the game crashes and when rebooting, the pack opens but there are no options so i'm softlocked.
