Other mistake: "Blue" checks out Cara Dune's record and talks to her in stellar terms, obviously she's a great gal. When Mando and her met in episode 1-4, Cara said that if she even tried to board a vessel registered with the New Republic, she'd be captured and be put in jail for life.
Chapter 15: The Believer - S2-E7
Other mistake: Somehow during the episode Cara and Fennec, on foot, manage to get to the base at the same time as Mando, who is on a truck. Moreover, Cara is the one with Mando's armor in a sack, but when Mando emerges from Slave-1, he changed clothes, and he's back in full uniform.
Chapter 16: The Rescue - S2-E8
Other mistake: The highly advanced and powerful Dark Troopers, when faced with a closed blast door, punch it repeatedly with their fists rather than simply prying the two doors apart. Even having dented it slightly, they don't wedge their hands into the cracks to open it, they just keep slowly denting it...more.
Chapter 16: The Rescue - S2-E8
Other mistake: The inexplicably omniscient Moff Gideon mentions that Mando fired his wrist launcher's "one and only salvo." This would confirm what could be assumed by the dialogue with the Armorer in episode 1.3: the Whistling Birds are rare, and made of Beskar. Mando uses them in 1.3 immediately, then he still has them in 1.6 to use them against Burg. He replenishes his ammo in the season finale so we can assume that includes the birds. In season 2 he uses them in 2.1 in the prologue and then in 2.6. Seems abnormal to say the least that he'd have still some to use in 2.8 with no more refills.
Chapter 16: The Rescue - S2-E8
Other mistake: Shoulder to shoulder, Cara Dune and Fennec Shand advance shooting Stormtroopers on a bridge. But look where Ming-Na Wen is aiming; she's never gonna hit anything in front of her, and if there's any threat all the way to the left where she is pointing her blaster, it is never shown. (00:14:50)
Chapter 15: The Believer - S2-E7
Other mistake: The final art of the credits shows Mayfeld jumping on the Slave-1 with Mando helping him. Mando is in his full Mandalorian armor though, which would have been impossible at that point of the story. (00:34:55)
Chapter 15: The Believer - S2-E7
Other mistake: The two heroes run away from the cafeteria through the side of the building. The snipers are luckily positioned with a perfect view on their fortuitous escape route and start killing people. When Mayfeld reaches the top, we see one stormtrooper getting hit by the sniper - but the laser beam comes practically from behind him, at an angle that appears not compatible with Fennec's position. (00:29:20)
Chapter 15: The Believer - S2-E7
Other mistake: When Juggernauts 3 and 4 are destroyed, the screams of the drivers and the explosions are practically instantaneous, it takes 5 seconds tops. When Mando and Mayfeld's truck is assaulted, the marauders take a much longer time to deal their damage. (00:13:00)
Chapter 15: The Believer - S2-E7
Other mistake: The first guy that tries to put a detonator on the rhydonium opens its container freely; the Empire is transporting its precious deadly explosive in unlocked containers! But later on Mando is struggling and the baddies have to use their pointed sticks to open the containers.
Chapter 14: The Tragedy - S2-E6
Other mistake: Ahsoka tells Mando the name of a planet. Just the name and nothing else, we see him take off. It's a rather big planet as we can see from the atmosphere, and the Jedi temple is secret...yet Mando right away just finds "the big rock" in a planet with a complex sorta Earth-like geography.
Other mistake: In the first kill we see Ahsoka perform on-screen, the lightsabers don't cut anything, which is impressive since they leave scorching burn marks into a tree a moment later. (00:02:20)
Other mistake: In the first episode of the first season, the Stormtroopers in Nevarro were wearing poorly maintained and rusty uniforms, implying they were a small detachment stranded away and cut off from any remnants of the Empire, in fact living in a clandestine condition. They also had to set up a small laboratory in the bunker where the doctor worked. Now turns out that a few minutes off the city, there's a full base the locals were aware of, with tons of equipment, that is where the stormtroopers from Season 1 finale came from, and that the research facility is there.
Other mistake: Cara Dune rams with the Marauder a trooper who was shooting at her through the open window. The speederbike explodes in a ball of flame, but despite the big open window that goes through the whole length of it, the flames do not affect the inside in the slightest. (00:25:50)
Other mistake: The imperial base (that has been there for a long time) has troops on speeder bikes ready to launch, but no proper way for them to get out of the base itself, so a couple of them die just because the jump is too steep and they can't avoid the rocks! Imagine building a garage ramp 40 feet in the air and not even clear the ground underneath from huge sharp rocks. How would they even go back up? There's no towing equipment in sight. (00:24:45)
Other mistake: Greef Karga mentions that the Mythrol was his accountant before running off, but when Mando captured him in the first episode, he had no idea who Mando was nor had ever seen his ship before.
Chapter 11: The Heiress - S2-E3
Other mistake: Mando's ship is completely devastated, gaping holes in the hull, patched up fuel lines, engines malfunctioning, and on top of that entirely flooded. The Mon Calamari repairs it for 1,000 credits and the protagonist acts like he's been ripped off. When Mando in season 1 turned down the bounty for the guy who missed bail, Greef Karga offered him 5,000 and Mando replied that it does not even cover fuel. As exaggerated as it could have been as a statement (he was complaining and perhaps haggling a bit), and as bad as the repairs prove to be, 1,000 sounds disproportionately small for repairs on massive structural damage AND refuel.
Chapter 10: The Passenger - S2-E2
Other mistake: When the Razor Crest is beginning to fall, a shot shows the interior of the ship; the cargo is entirely unsecured and the eggs inside tumble all over the canister with no dampening to their inertia. The motion shown was just a mild tilt of the ship from one side to the other as the ship was about to fall. To imagine the cargo staying intact in those conditions during the manoeuvres shown before, which were tossing the frog lady in the cockpit all over the place, is inconceivable. (00:16:50)
Chapter 9: The Marshal - S2-E1
Other mistake: The acid the dragon spits is purported as highly corrosive, literally melting people, however Mando is unaffected by it despite being bathed in it. His armor might be Beskar, but there are plenty of spots (those that his enemies constantly seem to miss) that are not. He should be at least in some discomfort and in need to change, and not carry around his neck a cape soaked in venomous dragon vomit.
Chapter 15: The Believer - S2-E7
Other mistake: Before the tunnel the truck drivers communicated with the base, and the base itself is warning another vehicle about their speed. Despite this level of monitoring, the heroes board the truck taking their sweet time to change in suits and have friendly banter. Considering the convoys are attacked frequently by terrorists, it's hard to imagine that a large discrepancy of that kind would have stayed unchecked.
Chapter 16: The Rescue - S2-E8
Other mistake: Moff Gideon is holding the Child under the threat of the darksaber. He tells Mando "Drop the blaster." Mando killed the two last enemies with his spear (the second one even choking him with it) and went straight to open the door of the cell, no blaster in hand. (00:20:00)
Suggested correction: The reason why the Dark Troopers didn't wedge their hands through the door was because during that time the door was already closed shut when they arrived at the bay door. If you watch at the beginning where Mando was trying to close the door before the Dark Troopers and exit their station but as Mando was closing the door the door wasn't fully closed but it was closing, so a Dark Trooper used its hand to open the door while the door was closing. If the door was closed then they would have punched their way through. And as you can see if you watch one dark trooper escaped but the others had to punch their way though.
Not my point. They manage to dent the door easily enough. So when faced with a closed door they could have made a dent, then put their hands into that crack to pull the sides apart. But they don't, they just keep slowly hammering it. They weren't punching through, just denting it, pointlessly.

The first Dark Trooper also punches the Mandalorian's helmet repeatedly instead of any other fighting move, and the Dark Troopers try to punch their way through the blast doors on the cruiser's bridge instead of cutting, tearing or shooting their way in. It seems their programming is limited in this way. This is still a mistake but it becomes a deliberate mistake or a character mistake.
