There is a bug which makes the game unbeatable by permanently removing a card. It went like this - if there is a fire at the beginning of the turn, and you quickly open your warehouse and try pulling an item, the item will get permanently stuck in the front of the screen and just stay there. It no longer exists in the warehouse or the deck or the hand. If you refresh the page, the card is gone from the front of the screen, but doesn't reappear in the warehouse or deck. I lost a "Drilled Well" card this way and can no longer start an upgrade. I have all other upgrades in the game completed, except one that needs this item.
