discovered game breaking bug, 5 cards could hard lock the game (2x trashcan, 3x machine), immediately breaking it. As result: 8 cards removed from the deck (2x trashcan, 3x machine, 3x cog), and replaced by 8 other cards expanding the number of those cards in the deck (2x portal, 2x grating, 2x key, 2x lockpick)

game start: each player get 9 cards instead of 7 (prolongs the game, prevents winning outright in third round).
