Continuity mistake: After Anakin and the most recently mutated Nelvaanian free the other mutated, the latter puts his hand on one of his fellow's shoulder. When he does, the control harness the two should have destroyed earlier is still on; in the next scene right after, the harness is gone.
Other mistake: When the most recently mutated Nelvaanian tries to show Anakin how to free his tribe mates, the second Nelvaanian he rips the control harness from, suddenly has his implanted left arm blaster missing; instead his hand - which should have been amputated - appears.
Continuity mistake: When Mace Windu intercepts Grievous at the latter's gunship, Grievous activates his lightsabers while standing on the ramp to his ship's hatch. But when Windu crushes his chest and Grievous starts to cough, he is suddenly standing right inside the hatch.
Deliberate mistake: When Mace Windu jumps aboard the gunship and orders the pilot to turn around, and the pilot replies with "Yes, sir", there is a blaster cannon mounted in front of the pilot canopy. However, LAAT gunships do not have a blaster mounted right before the canopy. This shot evidently comes from the scene in Chapter XXIII where Windu rescues an ARC-170 fighter from three vulture Droids.
