Other mistake: Look at the tombstones in the cemetery. I counted the name Carl Unger 4 times. Also the order of the tombstones changes several times. (00:14:30 - 00:16:10)

Question: Does anyone know why Piney wears a jean vest instead of leather like the others?
Chosen answer: The First 9 wore these, as can be seen on old pictures. They later switched to leather, but Piney just never did.
