Started a run yesterday, played on and off and beat the Ante 8 boss blind right before bed. I went to sleep, then kept playing this morning in Endless Mode until about Ante 10 or 11. I finally lost, and went back to the main menu to see the new deck since it was my first win with Yellow. I saw the popup/modal showing that I unlocked the Ghost Deck. I tapped Close or whatever the button is, tapped New Run, and the deck is still locked. Also appears that it didn't appear to save any of my stats, including Most Money (says $54 but I was well over $100) and Biggest Hand (says 150k but I know I had at least one that was around 190k).

Similar issue with checkers but without pause inbetween. Remember what jokers might have been involved? For me notably for the first time on mobile: Midas and Vampire.
Also: did you get the achievement for the win on arcade?
