Continuity mistake: Kenny's hair goes from being light-brown to blonde. (00:05:50 - 00:11:00)
Continuity mistake: When Kirkland is going through photos of Rogue, he stops on a photo of the full X-Men team. When the shot changes, the photo he is stopped at is of Rogue and Cannonball. (00:08:25)
Continuity mistake: Gambit uses his staff to pole vault himself across the rooftops. When he lands, the staff has vanished. (00:09:30)
Other mistake: When Gambit pushes out the vent shaft cover from inside the ventilation system, his hands emerge gripping the outside of the cover. This would be physically impossible. (00:09:55)
Continuity mistake: When Gambit jumps out of the ventilation shaft, there is no one around him. Then he is suddenly surrounded by guards who could not have converged on him so quickly unless they appeared out of thin air. (00:10:00)
Continuity mistake: When Gambit is restrained in the chair, his gloves alternate between being his usual gloves that are fingerless at the thumb, index and pinkie fingers, to not being fingerless, to him not wearing any gloves at all depending on the shot. (00:10:05)
Continuity mistake: The ice cream that Cannonball drops when Kenny confronts him disappears in subsequent shots. (00:10:50)
Continuity mistake: In one shot before the nurse shaves a patch out of Gambit's hair, the neck portion of his black headgear is flesh-colored. (00:12:40)
Other mistake: When Rogue rendezvous with Beast, Xavier and Gambit, she pinches Gambit's cheek with her bare fingers. This should have caused her to drain his powers and render him unconscious. (00:14:10)
Audio problem: When Mr. Guthrie is saying "I worked with you inside the mines and shopped in your stores," his mouth is completely out of sync with the dialogue, sometimes not even moving at all. (00:14:45)
Continuity mistake: When Moira is asking the X-Men how they intend on contacting Lilandra, Jean Grey's face is colored yellow. (00:05:10)
Continuity mistake: When Trish Tilby is giving the news report, she is first shown to be in front of a gray news van. When the shot changes and for the rest of the report, she is standing in front of a blue screen. (00:05:30 - 00:06:45)
Continuity mistake: When Cyclops, Wolverine and Gambit are watching Morph giving a statement on the news while masquerading as Xavier, Cyclops' hair looks like a bowl-cut rather than the usual semi-shaggy look he sports. (00:06:20)
Audio problem: When Magneto is saying "I have heard your cries for justice and I now answer that call," his mouth is not moving. (00:11:45)
Continuity mistake: When Magneto is saying "You are the next step in man's evolution," the lower half of Sunfire's mask is flesh-colored. (00:11:55)
Continuity mistake: When Jean Grey is stating how Magneto's powers intensified her own, the left side of her costume around her abdomen is colored yellow whereas it is usually blue (the right side remains blue in this shot). (00:13:30)
Continuity mistake: When the camera pans around the team after Lilandra saves Xavier, Storm's communicators are colored white whereas they are normally red, and Rogue's gloves are missing below the wrist. (00:18:50)
Answer: It appears a number of factors led to its demise. It was originally intended to air for 65 episodes, but its popularity extended that. However, there were continual production quality problems, issues regarding whether the content was suitable enough for children, as well as financial considerations that finally led to it being ended.
