Chapter 1: The Mandalorian - S1-E1
Continuity mistake: "The blue guy" puts his credits down on the table hoping to buy his freedom from the hunters. Next time the Mythrol and his captors are in frame, gone are the credits from the table; actually you can see them again when the mug is knocked off the table, but in that case, they were in the wrong spot, for the mug to be blocking them from view. (00:00:55)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: Once Mando delivers his trademark "cold/warm" line, the bounty puck changes position on the table. Conversely, his hand position is the same, but delivering the line he had dramatically put it to his holster. (00:03:00)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: Mando meets his contact at the guild to get paid. Watch as he gets seated; on the table, there's a pile of little tiles. And then, his guy puts down on the table...that same pile of colourful Imperial credits. The position of the beeping locating devices changes too. (00:11:05)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: When Mando's contact puts down the Calamari flan chips, one of the imperial credits is separated from the rest of the pile, but not in the close-up. (00:11:25)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: When Mando points his weapons at the Imperials after the Pershing jumpscare, the strap of his rifle is swinging in the wider shots but it rests still against his wrist in a different camera angle. (00:14:50)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: Imperial hideout. A person enters the room causing (for some reason the bounty hunter is way jumpy over a normal door) Mando to pull his gun(s). When the boss introduces him saying "This is Dr. Pershing", the stormtrooper by the door is lowering his weapon, but he's still pointing it straight at Mando in the reaction shot of the doc. (00:14:50)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: When Herzog mentions a "less traditional agreement", the Beskar ingot is gone from Mando's hand (but it's still there in the shots before and after). (00:16:05)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: When Werner Herzog introduces termination as an option for the subject, the cloth he had the Beskar wrapped in is not creased against the object on his desk any more. (00:16:05)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: Having got the mysterious mission from the Imperial, Mando heads back home to his not-really-so-secretive commune with kids and everything. When he gets in sight of the blacksmith character, he is putting down his long, staff-like weapon. From behind, he is switching it to his left hand, but in the reverse shot he is using his right hand. (00:18:50)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: When the Mandalorian is learning to tame the blurrg his leg armour changes from right to left and back again. (00:26:10 - 00:26:45)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: When IG-11 shoots the first batch of criminals, the natural light changes between shots. Look at the aerial view immediately before Mando's arrival; the robot is casting a distinct shadow at 7 o'clock and the corpses to the right are next to the shadow of the building. All different from the shot that follows. (00:29:30)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: When Mando steps back from the cannon to look at the destruction he laid, in the close-up the freshly remade pure Beskar pauldron is on the wrong shoulder. (00:33:35)
Chapter 1: The Mandalorian - S1-E1
Continuity mistake: IG-11 runs its diagnostic, and then tells Mando the outcome. Between shots, the antenna/camera spinny things on his head are in different positions, and Mando is in two very different poses; his right hand was on top of his left wrist, his arm is lowered in the second shot. (00:34:00)
Continuity mistake: When the Child looks at Mando with commiseration after the fall from the sandcrawler, his ears are lower or higher depending on the shot. (00:09:25)
Continuity mistake: Mando dropped the blaster gun and just stepped out of the trailer to join Kuiil with the jawas. The Child is looking at him, but from a different spot between shot and reverse, as you can notice by the gaps in the railing. (00:14:00)
Continuity mistake: The jawas are about to leave; during the scene, the position of the shadows on the ramp of the sandcrawler keeps changing between shots. It is subtle at the beginning when it's just Kuiil, but as a battered up Mando returns with the egg, it's very apparent. (00:22:00)
Continuity mistake: When Mando repossesses the knob, the Child's ears go from straight to floppy in the space of a camera cut. (00:02:30)
Continuity mistake: The Client tosses the fob on the desk. He then fetches the pot of Beskar and puts it on the desk, but the fob changes position. (00:06:05)
Continuity mistake: The pile of beskar in front of the Armorer changes wildly in size and distribution depending on the camera angles. (00:09:15)
Continuity mistake: Mando knocks at the door and grabs the rude TT-8L/Y7 gatekeeper droid, ripping the eye part out entirely, nothing left on the arm. Mando then gets out of the Imperial hideout, he does it from the front door. By the door, but the security device has its eye back, still dangling off a cable. (00:19:55 - 00:24:30)
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.
