Continuity mistake: The headless android falls into a pile of rubble after an explosion, getting up with its red, white & blue striped costume in smudgy tatters. A moment later, its outfit is mended and completely clean. Still later, when the android is walking outside, its costume is dirty and shredded again.

Continuity mistake: Just before Scorpio crashes, Avon grabs Orac and teleports to safety. When they're still aboard the ship, Orac has several wires hanging loose from underneath. When they materialize on the planet, however, all the loose wires are magically repaired and no longer hanging.

Continuity mistake: Vila makes an improbable costume change in this episode. He's wearing one outfit at the end of "Terminal," when Liberator is destroyed, and another outfit entirely here, where he's supposedly marooned on the planet with the remainder of the crew. Did he take time to smuggle a spare set of clothes off the ship, even though it was disintegrating at the time?
Continuity mistake: When Avon & Co. barnstorm the ruined lab, a large piece of plastic debris on the floor is there when they enter, but then disappears between takes. Avon actually slips on it coming in, and does a hilariously un-macho little balancing dance. To quote (and agree with) actor Paul Darrow: "I can't believe they left that in!"
