Continuity mistake: When the bad guys from Sweetwater county try to steal Boss' safe, you see them pushing it up a ramp into the pickup truck. But in the next shot, when Daisy calls the operator, the safe is in the corner. And when Bo and Luke go to untie Daisy, the safe is gone.
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)
Plot hole: Char is able to escape from Side 7 simply flipping a couple grenades he had on his person (shaped like the old style pineapple grenades) who tear huge holes into metal walls with a visible thickness in excess of a meter, including the outer wall of the space colony a salvo of Mega Particle Cannon from the battleship didn't break. If Zeon has such explosives at their disposal, then maybe they should not fight with battleships and giant robots, but simply have footsoldiers toss tiny grenades at the enemy. (00:15:00)
Continuity mistake: At the Chequers meeting in early 1944, Sir Bernard Montgomery is wearing the rank insignia of a field marshal. In the later meeting with the King in which the D-Day plans are announced, he is correctly wearing that of the lower rank of general. In fact, Montgomery was promoted from general to field marshal on 1 September 1944, nearly three months after D-Day.
Plot hole: It's all very well for Albert to humm "bzz-bzz" to indicate that he has been eating too much Royal Jelly and is no longer entirely human. But "bzz" is just the noise of bees flying, it's not a sound that they deliberately produce. It makes no sense to SAY "bzz." Suppose he was turning into a horse instead, then he might say "Whinny!", but he wouldn't say "Clip clop clip clop."
