The Ghost of General Lee - S2-E6
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.
Continuity mistake: When we see the pizza stand at the beginning, you can see there is nothing on the counter when the Mystery Machine drives past it. But when Scooby goes up to the stand, a plate of rolls and a napkin holder with two pots have appeared.
Planet of the Slave Girls - S1-E2
Continuity mistake: When Buck goes to run out of the door of the factory, it's a solid door, with a bar-type handle. When the scene shifts to the outside, the door he runs out of leads directly inside, but the door has vent slats on the lower half, and the handle is completely different.
