Continuity mistake: When the crew go through the stasis leak for the first time, the Cat walks through, then Rimmer waits before jumping through. When they appear on the other side, they fade in together.
Visible crew/equipment: When the crew are standing before the Judgement computer (when Lister is worrying that he will be sent to prison) if you look above Lister's head you can see a microphone bob up and down into shot.
Continuity mistake: When Rimmer picks up the bazookoid at the end of the episode and runs into the engine room, the gun is pointing up. In the next shot from inside the engine room, it is pointing down.
