While Chopper is moving across the desert of Tatooine, he only leave two tread marks even though his middle wheel is also being used.
Ezra arrives on Tatooine armed with both his lightsaber and blaster, yet uses neither of them when he and Chopper are set upon by Tusken Raiders, resulting in the destruction of his ship.
The Rebel officer discussing the munitions with Ezra refers to him as "lieutenant." Ezra is a lieutenant commander. The proper way to address someone of that rank is either as lieutenant commander or just commander, but never as lieutenant.
