Continuity mistake: Grant begins to remove the screws from the vent starting from the right side, but the top row is already missing and unscrewing 2 on a single side already makes the vent wobble significantly before the camera cuts away. (00:14:00)
Piratsy Under the Seas - S1-E1
Continuity mistake: When Jolly Roger hands the map to Dale, the map has either a dark brown border or not depending on the angle. (00:08:30)
