Klondike Solitaire - impossible deck

Solution 1:

To just put an answer here, assuming that the jack on the waste is indeed the last card in the stock, it's a bug.

Klondike Solitaire is played with one full deck of cards consisting of 52 cards, A to K of 4 suits. In that screenshot above, you have 11 cards on the Foundations, 1 card in the Waste, and 32 cards on the tableau, which totals to 44 cards.
