When Mando and his team break into the Imperial lab, Cara raises her blaster. When the shot cuts to the officers inside and back, she raises her blaster again.
(At around 32 mins) Cara Dune is leaning on a post outside, talking to the rebel pilot. When he drops the pin on the table, she straightens up, but in the next shot she is leaning against the post again.
When Cara Dune shoots the last Aqualish thug, her hair is parted on the wrong side and her drop soldier tattoo on the wrong arm (flipped shot).
In the end scene, where Moff Gideon is talking to the officer, a scientist can be seen right behind him, checking on the Dark Trooper, but in the next shot that shows the whole room, there is no one there.
At the 21:41 mark, a Stormtrooper on the right moves in a disjointed manner back and forth. This appears to be an editing malfunction.
When Cara Dune takes down the Aqualish at the 4:55 mark, a beige crash mat can be seen for two quick shots. It's also placed on top of a grate so it sticks out very well.
At the 18:54 mark, a crew member wearing blue jeans, a t-shirt, and a wrist watch can be spotted standing partly behind the door entrance on the far left of the screen when Greef Karga, Cara Dune, and the Mandalorian fire their blasters at the Imperial scientists. This has since been corrected on Disney+.
