In The Book of Boba Fett, just months prior, Paz Vizsla tells Din Djarin, "There are only three of us left." In the opening mandalorian baptism scene, there are between thirty to fifty mandalorians in attendance.
The amount that the metal is bent changes drastically between the final shots in the opening forge scene, even appearing completely unbent after a shot in which the metal is dramatically crumpled.
IG-11's depiction here is inconsistent with how he was depicted in the first season. Here, he defaults to his programming to kill Grogu, but in the first season all of his programming was wiped and he had to relearn even basic functions from scratch. He self-destructed using a thermal detonator located within his chest, yet his chest and head here are intact while most of his limbs are shown missing. A self-destruction that leaves enough material intact that he could be restored to working order is not very effective and goes against his statement that his manufacturer's programming said that he could not be captured.
