The Alexander the Greater Affair (1) - S2-E1
Character mistake: When Alexander organizes the human chess game in his courtyard, the "pieces" stand the wrong way on the board, with a dark square in the lower right hand corner. That corner is always a light square. (00:22:50)
Continuity mistake: When the door of Pod 1 opens after Jeff realises there is a saboteur on board, we see three vehicles in the pod and beside the Monobrake there is a red unit which has a windshield on it. However, when we see Chip appearing in the next shot, the windshield has gone.
