Savage Land, Strange Heart (1) - S3-E8
Revealing mistake: When Zaladane is helping Sauron escape, she uses her staff to reveal a hidden stairway in the floor. As Sauron descends the steps, the opening fades back into resembling the floor to suggest it is being hidden again, but Sauron fades away as well. It should be that Sauron walks out of view, and then the opening fades back into the floor. (00:02:56)

The Dark Phoenix (4): The Fate of the Phoenix - S3-E14

The Dark Phoenix (4): The Fate of the Phoenix - S3-E14
Revealing mistake: In what appears to be an animation error, when Cyclops shoots his optic beam after he and Jean emerge from hiding, his bandolier is absorbed into his uniform. (00:14:25)

Revealing mistake: When Moira gets up from her seat to check on Xavier, her left leg passes through the left armrest. (00:14:45)
Revealing mistake: When Proteus is leaving his father's home while possessing the police officer, the green glow of his eyes doesn't stay in place as he is moving.

It appears that the animators couldn't keep the glowing eyes synchronized with the body movement. (00:07:30)
Beyond Good and Evil: Part 1 - S4-E8
Revealing mistake: The slice of cake that Wolverine cuts out already has the cut-lines animated on it before he starts slicing it. Probably to make it easier for the animators to animate his hand movement. (00:11:05)
