Suppose I select a New Run, set the difficulty for the current deck to Red Stake (i.e. level 2), then briefly change my mind and switch decks, to either a deck that hasn't been unlocked yet or one that hasn't unlocked Red Stake. Then I change my mind again and go back to the first deck where I'd previously selected Red Stake.
What should the selected difficulty level for this deck be? Imo it should be Red Stake, but it actually resets to White Stake.
