Deliberate mistake: "The Creature's Revenge" (Adventure 3, Part 5): The 2-inch heels on Sapphire's bright blue boots disappear and reappear repeatedly. They're most often missing in the scenes she appears in with Steel, presumably so that her height won't exceed his. (00:15:15)
Continuity mistake: "Railway Station" (Adventure 2, Part 4): Steel's crooked bow tie straightens itself out between takes as he's confronting the soldier's ghost. (00:04:00)

Revealing mistake: "Dr. McDee Must Die" (Adventure 5, Part 3): When the champagne glass shatters in front of Sapphire, you can see the mini explosive charge used to break it. It lands on the table among the glass shards. (00:10:00)

Revealing mistake: "Railway Station" (Adventure 2, Part 3): Steel orders Tulley to light all of the abandoned station's lamps with matches.

Continuity mistake: "Service Station" (Adventure 6, Part 2): After the 1940s couple arrives at the diner, the tomato-shaped condiment dish keeps migrating to different spots on their table, even though no one is ever seen touching it. (00:19:30 - 00:22:50)
Revealing mistake: "The Creature's Revenge" (Adventure 3, Part 2): This apartment building has unbelievably clean elevator cables. Steel takes off his coat and then ties a knot in the cable - without getting a single grease smudge on his hands or his pristine white shirt. (00:06:45)
