Continuity mistake: The Scout Troopers have finished their shooting game. One of them gets up and the other looks bored (and annoyed because he does not get to see the 'package'). He is leaning against the bike's handle, or not, depending on the shot. (00:04:10)
Continuity mistake: After the comedy skit with the two scout troopers is over, the ground in front of Moff Gideon is in the shade or sunlit depending on the camera angle. (00:06:00)
Continuity mistake: When the nerdy Moff namedrops Mando and Greef's real identities, the shots from the waist up are mirrored; look at the position of the buttons on his Darth Vader-esque chestplate. (00:08:30)
Continuity mistake: When IG-11 is making its way through the city with a cartoonish trail of explosions, Greef Karga is having a drink. There's a sudden cut, and in the second shot the glowy liquid in the bottle is bouncing around very noticeably as if the bottle (or the whole counter) was just moved/knocked, which did not happen in the previous shot. (00:15:45)
Continuity mistake: When Greef Karga follows Mando outside the cantina to go support IG-11's sortie, he comes out of the door which has a large shadow area to the right of the frame, gone in the next camera angle. (00:16:25)
Continuity mistake: Somehow without being challenged, the imperials put explosive on the door of the cantina and blow it open, nearly flushing out Cara. More pew-pew action ensues, Mando is critically wounded, and his pals drag him back to the cantina and...close the door behind them. The building grew a door back? (00:17:05 - 00:18:30)
Continuity mistake: The door of the bar Cara Dune is hiding in, is blown out of the doorframe by a trooper, but later it's back and fully repaired, and IG-11 closes it. (00:17:21 - 00:18:31)
Continuity mistake: Moff Gideon is able to best Mando also because he turns twice; he already has brought the heavy E-Web machine gun from shoulder level once, but Gideon notices the power unit and switches target when Mando is repeating the movement. (00:18:05)
Continuity mistake: Greef Karga moves his coat to access his holster, which is empty, until it isn't. (00:26:47)
Continuity mistake: When Mando switches on the jetpack, the reaction shot on Cara Dune is flipped. In the same shot, Mando also has the jetpack mistakenly still in hand, but he already put it on his back. (00:38:15)
Continuity mistake: After getting pulled and ragdolled around by it, Mando lands on the TIE fighter somehow with still both arms and decides to start shooting Moff Gideon. When he splats like a fly on the cockpit window he has nothing in hand, but at the cut he suddenly has his gun. (00:38:40)






Chosen answer: They could be just like wrinkles from age, like the elderly Togruta in the Zygerrian slaver arc in The Clone Wars series, as Ahsoka is considerably older than her animated appearances. I think there is probably a character design/stylisation aspect to it as well - the other Togruta we've seen in live action, Shaak Ti, has four segments or folds in her lekku that were not visible in her Clone Wars appearances, so it would seem the character design in Clone Wars and Rebels reduces such features.
