Revealing mistake: As Gaal is mourning Salvor, the camera is panning back, and everyone gathers around. You can see the little boy that died lift his head slightly. (00:37:17)
Twice the Grieving, Double the Loss - S1-E7
Revealing mistake: When Jake screams "Talk to me!" at the doll in the station and it says "Hi, I'm Billy! Wanna play?!", you can tell the reflection of Jake in the plastic has been added in post. It unnaturally wobbles a little bit at the end of the shot, especially his shoulder area. (Looks like they tried to motion-stabilize the shot used for the reflection a bit, which can sometimes make a weird "wobble.")
Outlook Good - S3-E1
Revealing mistake: The cups of coffee that Ravi brings are blatantly empty.
Chapter 7: In the Name of Honor - S1-E7
Revealing mistake: When the big battle starts, Boba and Mando appear using their jet packs. As Boba lands with one foot forwards, sand is thrown up into the air, but the sand is a special effect coming from about a metre in front of Boba, not from the foot itself. The result is very unconvincing.
Revealing mistake: When everyone is supposed to be frozen, the neighbor girl standing behind the car can be seen moving her hand onto the car. This happens as Monica says "I'm not afraid of you, Wanda." (00:24:25)
Dinner Party - S1-E4
Revealing mistake: Issac is reflected in the cabinet door when Sam is asking for the ghost's help.
Suggested correction: When was it established that the ghosts' reflections aren't seen?
Revealing mistake: When Caleb arrives, as he's talking to Billaba and Grey, his Padawan braid clips through his cloak as it sways back and forth. (00:02:05)
Revealing mistake: Whenever the newspaper Josh is shown at the beginning appears, the news story consists of a paragraph that repeats itself.
