When Black Krrsantan returns to the cantina, he is already limping, then gets shot into the knee and can't stand without help. Shortly after that, he is running down the street.
The size of the Rancor's head keeps changing. At first it is large enough to put a full sized Pyke in its mouth. Later, when it tries to do the same to Mando, it can barely fit the Mandalorian's helmet in its mouth. Later still, when the beast is soothed by Grogu, it appears to have shrunk in size even more.
The Mandalorian is holding and firing his blaster in his right hand when Peli Motto arrives in her Rickshaw. He grabs on to the vehicles with both hands, but in the next shot, which is flipped, he has the blaster in his left hand. Then it cuts to another shot and now his blaster is in his right hand (because this shot is not flipped).
Boba Fett's gaffi stick changes lengths from when he is wearing it on his back while seated on the rancor to when he wields it in battle against Cad Bane.
When Boba Fett is thrown from the rancor's back, in a couple of the shots where he is falling, the blaster is missing from the holster on his right hip. In all other shots before and after, it is present.
