Continuity mistake: During the Cat's dance scene with Blue Midget, we see one shot of Blue Midget doing the air guitar move, but in the next shot, his arms are not visible at all. It changes between these two differing shots throughout the closing end of the dance routine. (00:10:10)
Continuity mistake: When Bird-man loses his glasses, he is feeling his face. In the next shot both of his hands are on the floor. (00:25:40)
Revealing mistake: Just before the Cat starts his dance, Kochanski is at the back of the cockpit of Blue Midget and is bouncing up and down, yet the ship is not moving. When it starts moving, Kochanski is sitting still. (00:08:05)
Plot hole: As the luck virus gets you what you want, it should not have cured Lister of the sexual magnetism virus when Kochanski was all over him. (00:16:25)
Suggested correction: According to the Red Dwarf Fandom page, "The Sexual Magnetism virus makes the infected irresistible. The only known anti-virus is the Luck Virus, which was discovered by accident by Dave Lister." Granted, it doesn't seem to make sense, but apparently that's just the way it works.
Visible crew/equipment: In the cell at the start of the episode, after Rimmer says they have to escape, a boom mic is visible at the top of the screen. (00:03:10)
Continuity mistake: When the Cat does his tap dance, he starts 20 feet away from Blue Midget and does not move from his position during the dance. When he finishes, he taps Blue Midget's leg. (00:09:30)
Revealing mistake: When Kryten's hand inflates and flies away, his forearm bends in the middle. (00:06:40)
Visible crew/equipment: After Rimmer injects himself and speaks to Captain Hollister, a boom mic can be seen at the top of the screen. (00:26:25)
Continuity mistake: At The End of "Nanarchy" Starbug 1 flew underneath Starbug 2 at The End of the episode, yet in this episode when the scene is repeated, the ship flies around Starbug 1 instead. (00:05:50)
Continuity mistake: When the virus starts to eat the potatoes, Rimmer picks them up from the pile just below eye level. In the wide shot it shows the potatoes are just below waist level and Rimmer would have had to lean much further away from where he was standing to get the potatoes from that height. (00:20:00)
Revealing mistake: When Rimmer is typing on the keyboard, what he is saying does not match what he is typing. He is typing randomly. (00:12:20)
Continuity mistake: When Starbug crashes through a vent, Lister leans to his far right. In the next shot, he is leaning to his left. (00:09:20)
Revealing mistake: When Baxter puts the Cat's head in the drinks machine and says hot bovrill, Kryten can be seen mouthing the line behind him. (00:22:20)
Suggested correction: Kryten is not mouthing the line "Hot bovril." He is just moving his mouth slightly up and down, which coincidentally happened to occur when Baxter was saying the line.
Continuity mistake: When Bird-man's boots drop to the floor, the crew are looking straight forwards. In the next shot they are all looking up. (00:26:45)
