Continuity mistake: Lister and Rimmer's bunk room looks exactly the same in the flashback scenes during this series as it does in the present time. In the first series it looked completely different, so surely the look should have changed slightly for the flashback scenes?
Other mistake: The shots of Blue Midget driving back to Red Dwarf that are shown from behind are visibly the exact same shots used each time. This is evident as the driving movements of Blue Midget, its position in the frame, and Red Dwarf's position in the background are all identical each time.
