The Phoenix Saga (5): Child of Light - S3-E7
Continuity mistake: When Ch'od asks Corsair what is happening, his normally green lips are colored white. (00:04:10)
The Phoenix Saga (4): The Starjammers - S3-E6
Other mistake: When the X-Men and Corsair encounter D'Ken in the hallway, D'Ken, Gladiator and Lilandra remain in the background while the X-Men and Corsair are wiped from the screen. It's as if this was meant to be a zoom in on D'Ken, Gladiator and Lilandra, but their size relative to the camera remained the same and the X-Men and Corsair are simply removed from view. (00:19:35)
The Phoenix Saga (5): Child of Light - S3-E7

The Phoenix Saga (4): The Starjammers - S3-E6
Other mistake: When Gambit is tossing playing cards in Lilandra's helmet, he is shown tossing four cards. All four cards are the exact same card (the ace of spades). (00:13:30)
The Phoenix Saga (4): The Starjammers - S3-E6
Continuity mistake: When Corsair first enters Cyclops' holding cell, the door says "Security Cell 3." When Corsair leaves the room, the door simply says "Security Cell." (00:09:00 - 00:13:15)

The Phoenix Saga (4): The Starjammers - S3-E6
Continuity mistake: In the group shot when Phoenix says "of lives beyond measure," Moira McTaggert's hair is blonde and Wolverine is missing his gloves. (00:04:25)
The Phoenix Saga (3): Cry of the Banshee - S3-E5
Continuity mistake: The yellow paint for the "H" marking on the helicopter pad on the roof of the Muir Island Research Center becomes smaller when the shot changes. (00:09:20)
The Phoenix Saga (3): Cry of the Banshee - S3-E5
Revealing mistake: When Professor X is telling Juggernaut that he is in his mind, if you look closely you can see there is a disembodied mouth on the right side of Professor X's face that is synchronized with his dialogue. Apparently an animation error. Note: this error may only apply to the DVD version of the episode, as it does not occur on the version of the episode that appears on Disney+. (00:04:00)
Continuity mistake: Wolverine's 5 o'clock shadow disappears and reappears throughout the episode.
Continuity mistake: Beast is present when Gambit destroys the Spirit Drinker. When Professor X arrives moments later, Beast is shown to be approaching the scene with him and then notes that the Spirit Drinker seems to be missing. (00:18:45 - 00:19:25)
Continuity mistake: Gambit is missing his gloves when Jean Grey stops him, Wolverine and Cyclops to tell them what Professor X told her about the alien ship. (00:15:20)
Continuity mistake: When Wolverine is trying to get to Professor Oyama, he slashes twice at the door leaving six claw marks. When the door is shown again after Wolverine is reacting to the explosion, there are suddenly several more claw marks without him ever slashing at the door again. (00:11:40)
Continuity mistake: The three tear marks in Wolverine's uniform from when Lady Deathstrike slashes him change position several times. When she first slashes him, the tear marks appear on his chest. Other shots show the tears to be closer to his abdomen. (00:13:50 - 00:16:00)
Continuity mistake: When Professor Oyama says "Adjust the feed accordingly," you can see in the reflection of Wolverine in his glasses that the device that has been on Wolverine's left leg throughout the scene is missing. (00:10:20)
Continuity mistake: When Professor Oyama is telling Dr. Cornelius to begin the adamantium feed, Wolverine is reflected incorrectly in Oyama's glasses (note the device on Wolverine's left leg). (00:09:50)
Audio problem: Gambit's bō staff starts making a twirling sound a split second before he starts twirling it. (00:18:40)
Answer: Chris Potter, the original Gambit voice actor, did indeed quit the role in the 4th season. His last episode was The Phalanx Covenant Part 1 so it seems reasonable that Fox would limit the use of the character even though it was recast. It doesn't appear that Potter left the role due to animosity, he stated in an interview that he wished to play Gambit in the first live action X-Men film.
