Plot hole: When Lawquane spots the droids in the field, he identifies them instantly as commando droids. But as he had left the Republic Army shortly after the first battle on Geonosis (the one which started the war) and has lived as a farmer ever since, and since the commando droids are relatively new (see "Rookies"), how can he know what they are? With his lack of battlefield experience, he should simply call them battle droids.
Triumvirate of Terror! - S3-E8
Plot hole: At the Amazonian contest, the stadium is full packed with people spectating the event. When Joker attacks their queen and Wonder Woman, they do nothing. No panic, no revolt, no riot, not even a sound. Yet Joker just knocked out their queen, turned the other Amazonian warriors to his side with Joker Gas, and took out Wonder Woman, all in front of them. (00:11:30)
