Darkness and Light: Part 1 - S1-E11
Plot hole: When Hulk and Banner have been physically separated by the nutrient bath, they are both wearing tattered pants. Given that Hulk and Banner were previously occupying the same body, this should not be possible. Hulk was the one that went into the nutrient bath, so if Banner's body was separated from Hulk, then Banner should be naked.
Suggested correction: It was done deliberately as a form of censorship. They didn't want to show Bruce's genitals.
Explaining why the mistake occurred doesn't invalidate it. Unless you're suggesting the nutrient bath also was able to duplicate the pants.
You realise a character can be drawn naked without actually showing their genitals (and/or breasts in the case of women), right? The Little Mermaid is a good example of this.
The Return of the Beast: Part 2 - S1-E2
Factual error: When Betty's humvee breaks down in the middle of the desert, she gets out and steps over a scorpion. The scorpion is shown to have 10 legs (4 standard legs and 2 pincers). Scorpions have 8 legs.
Suggested correction: A scorpion's pedipalps (their pincers) are not legs. Scorpions and other arachnids have 8 legs and 2 pedipalps.
