Other mistake: Just after Cally says that the pilot's death was "a misfortune," she stands and her chair scrapes noisily on the floor. The sound apparently startled Paul Darrow, causing the always-unflappable, nerves-of-steel Avon to flinch: the only time in all four seasons that he's ever seen, albeit briefly, to break character.
Other mistake: When Jenna teleports down near the end of the episode, she takes 3 bracelets with her. When they all teleport back up to the ship she still has all 3 bracelets on. Therefore Vila and Avon should not have been teleported up.
