I'm not sure what triggered it so I'm going to list a bunch of extraneous stuff probably, but in round 2 of a game on the Latigo Villa map, with the red joker in the discard, when I tried to reshuffle, it'd put about half the deck in the discard, a quarter in the deck, and a quarter in the upper left hand corner of the deck screen with about a quarter of the card back visible.
When I reshuffled after that, it would swap between having 11 Crows and 11 Tomes on top of the discard,but wouldn't properly shuffle. Stacking all the cards one by one on the deck area and shuffling shuffled the cards properly.
