Teen Titans (2003)

Employee of the Month - S4-E6

Plot hole: When Beast Boy finally brings himself to disable the Destruct-O-Tron, the hole he punches into the device to get inside is already visible when he is still bracing himself for the plunge. This background was simply reused for the scene where the device shuts down for good.

Plot hole: When Beast Boy hires at Meaty Meat, he takes away the ad "Human Help Wanted" from the window right next to the door, and when the Titans come by for a meal later on, the sign remains gone. But as the Nufu ship reveals itself and the restaurant clients panic, the sign is suddenly back in the same corner of the window, even though it is unlikely that the Nufu Source/Bob would take in more hired help and risk being discovered all too soon.

Continuity mistake: The high building behind the Mega Meaty Meat is revealed to be the Source's mothership when the facade peels away. But in later scenes it still has the facade on, still looking like the tall building from before.
