Saga of a Star World (2) - S1-E2
Character mistake: When Starbuck and Apollo cross-wire the lift to reach the lower levels, they forget to undo their handiwork. Convenient to the plot, this oversight allows Boxey to wander into the Ovions' stronghold and require rescuing.
Character mistake: When discussing Ensor, Avon says he'd spent 20 years of his life in hiding. Yet in 1-13 "Orac" Blake said he hadn't been seen for 40 years.
