Bug: When doing an auction with only one other player, if the player who did not host the auction wins and declares bankruptcy, the auction host's menu will still be displayed despite the fact that the game should conclude as only one player is remaining. If that player then declares bankruptcy, the game crashes.
Bug: London 2: Blimey!: When you reach the part with the rolling obstacles, sometimes, there is an animation error where the first one does not appear to be rolling; it slides horizontally across its path until it reaches the end of it.
Bug: At any breakable piece workshop except the Inventor's Lab, first build a piece. Next, break the workshop down. This will cause the piece you made to be embedded inside another. Then, rebuild the workshop by replacing any piece except for the embedded one and build another piece. Fourth, break down the workshop or break down or move the piece. The former choice will result in the game crashing instantly, while the latter will result in the workshop spawning Keflings, eventually leading to the crash of the game.
