Continuity mistake: When Kryten tells Kochanski he doesn't have a penis, he turns away from her. In the next shot you can still see Kryten on the right of the screen as he turns away from her again. (00:07:20)
Continuity mistake: When Kryten's head falls off it bounces with no velocity, yet in the next shot it is quickly rolling out of the door. (00:06:55)
Continuity mistake: When Rimmer walks down the corridor, his hair is a mess. When he enters the medi-bay it is tidy. (00:25:25)
Continuity mistake: When Kryten is restored to his factory settings, the woman is pressing buttons on the keypad. In the next shot, her arm is by her side. (00:17:40)
Continuity mistake: In the bathroom when Kryten says he does not want his corrupted files repaired, he holds out his arms. In the next shot when the guards stun him, they are by his side. (00:15:00)
Continuity mistake: At The End of the episode when Lister, Kryten, the Cat and Kochanski are dressed as the Dibleys, they walk into the corridor in a line and Kochanski stops when she bumps into the Cat. In the next shot there is a suddenly a space between them. (00:26:40)
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.
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: Just after Kochanski jumps on Lister, she stands up and says 'I don't know what got into me' with her hand on her head. In the next shot, her hand is by her side. (00:16:35)
Continuity mistake: When Rimmer shows Lister the luck virus and sexual magnetism virus, there is less than half of the liquid shown in the test tube for the sexual magnetism, but when Rimmer is about to go to Hollister's dinner later on, there is more liquid in the test tube. There was also only one test tube of sexual magnetism for Rimmer to use. (00:12:15 - 00:18:10)
