Continuity mistake: When Beast and Dr. Bohlson enter Carly's room, there is no breast pocket on Dr. Bohlson's labcoat. A couple of shots later, his labcoat now has a breast pocket with two tongue depressors in it. (00:02:25)
Continuity mistake: When the opening of the Astral Plane is first shown emerging from Mt. Kilimanjaro's Kibo summit, the summit is correctly depicted as being somewhat flat. Near the end when the opening of the Astral Plane is diminishing, the mountain summit is shown to have a pyramidal peak. (00:02:35 - 00:16:50)
Continuity mistake: The boomerang that Xavier uses to throw at the jungle warrior astride the pterodactyl appears from nowhere. While it probably belonged to the warrior himself, neither he nor the other warrior with him were shown to have dropped it when they swooped by and captured Magneto and knocked Xavier down. (00:20:15)
Audio problem: When Magneto is saying "Strange. What would restore your...," his mouth remains wide open and unmoved after saying "restore," which would make it impossible to then say "your." (00:19:45)
Audio problem: When Storm is saying "But I do know that his thoughts were with us today," her mouth isn't moving. (00:19:00)
Continuity mistake: When Wolverine falls down the mine shaft, debris is shown to be falling with him. A few shots later, there is no debris to be seen on the ground where he landed. (00:13:15)
Continuity mistake: Storm's eyes alternate between being brown and blue throughout the episode.
Revealing mistake: When Morph is saying "You never were very bright," part of his shirt collar has been drawn on his chin. (00:07:20)
Continuity mistake: When Storm and Rogue are flying towards Storm's village in Tanzania, at one point Storm's hands are colored white. (00:05:25)
Continuity mistake: The graphic of Africa that Beast and Jean are observing is horizontally stretched at one point. (00:02:50 - 00:03:50)
Audio problem: When Barbarus says "Get them!" he says the word "them" without closing his mouth. It's not possible to say "them" without closing your mouth at the end of the word. (00:20:10)
Continuity mistake: When Gambit places Bella Donna's ring on the ground, she is nowhere around it. When the shot changes, the ring is suddenly right next to her. Note: this mistake may only apply to the DVD version of the episode, as the version of the episode on Disney+ does have Bella Donna there when Gambit sets the ring down. (00:18:50)
Continuity mistake: When the External states the Guild of Thieves have dishonored the tithe, both the Thieves' and Assassins' tithe boxes are missing from their respective tree stumps. (00:17:10)
Continuity mistake: When the External is emerging from the water, the Thieves Guild's tithe box is missing from its respective tree stump. In the next shot, it is back in place. (00:16:30)
Continuity mistake: When Rogue flies back towards Gambit and Bella Donna, Bella Donna is standing behind Gambit. When the shot changes, Bella Donna is standing in front of Gambit. (00:15:35)
Continuity mistake: When the Thieves and Assassins guilds begin to skirmish, they start by trying to regain the weapons that Jean Grey telekinetically confiscated from them. A couple seconds into the fight and most of the weapons have disappeared altogether. (00:15:20)
Continuity mistake: When Gambit pushes Bella Donna over, she is on his left, and there is a tree stump on his right (out of shot). When the shot changes, she is up against the tree stump. (00:14:25)
Other mistake: When Gambit pushes Bella Donna down, the wedding veil that she was wearing comes to a stop in midair. (00:14:25)
Continuity mistake: When Gambit is looking at himself in the mirror while wearing a tuxedo, you can see in his reflection that he is barehanded. In the next shot when he removes the tuxedo, he is wearing his usual black gloves. Also, the rose on the tuxedo goes from being on his right side (reflection's left) to being on his left side just before he removes the tuxedo. (00:13:15)
Continuity mistake: In the first establishing shot of the Assassins Guild's mansion, there is a stairway leading up to the front door. In the establishing shot of the mansion in the scene where Gambit is in Bella Donna's bedroom, the stairway is missing, and consequently the mansion's porch area isn't as high off the ground. (00:09:20 - 00:13:20)
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.
