Factual error: During the Battle of Teth (the pillared jungle planet), the AT-TE's shoot the ledge at the top and there's not a single mark in the ledge afterward despite being hit with several joules worth of fire.

Continuity: When Asajj Ventress starts to make the clone trooper move up the wall (before asking where Anakin is), her eyes are green as she raises her fist at him. When she uses the mind trick and tells him to contact Anakin, her eyes are blue.

Factual error: During the Battle of Teth, a walker fires at one of the pillars. In the next shot, it hits the very top ledge. Problem is it was actually aiming at the middle, as was the other walker.
