Deliberate mistake: At the beginning, Asajj Ventress is wearing an outfit with a long skirt. When she is rescued from her damaged starfighter by the scavengers, the skirt has vanished. This was done because the animators found the skirt too difficult to animate. This is also why she receives a brand new outfit that never had a long skirt later in the episode.
Continuity mistake: When Anakin is cutting through the door of the Kadavo facility after Master Plo's forces have arrived, the position of the hole he's making is different from when it was previously shown. When he finishes cutting the hole and kicks in the cut-out section of door, the hole is back in its original position.
