Other mistake: When the helicopters are attacking Magneto, they are firing their guns at him, and then he destroys them, at which point you can see the occupants parachuting away at the same time the helicopters explode.

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.
