Other mistake: Obi-Wan Kenobi discovers the Mandalorians and gets into a fist fight with them, punching one in the face a few times, who reacts with obvious discomfort. But the one hit is wearing Mandalorian armour, famously resistant to all kinds of weaponry, and Obi-Wan is barehanded! The Mandalorian should be laughing off his attempts. Not to mention that later he surprises another armed guard in Mandalorian armour and knocks him out with two barehanded blows to the helmet.
Suggested correction: It must be pointed out that unlike the Mandos he's fighting, Obi-Wan explicitly has supernatural powers, powers that most certainly help with things like punching out people in full armour. Seeing this as a "mistake" is kind of ridiculous in a space fantasy series.
