Savage Land, Strange Heart (2) - S3-E9
Audio problem: Sauron's mouth is wide open when he says "What is happening to me?!" (00:17:50)
Savage Land, Strange Heart (2) - S3-E9
Continuity mistake: When Storm breaks off communication with Beast, the animation suggests that she is removing the communicators from her chest, but they remain in place. A couple of shots later, they are completely gone. They then reappear and disappear throughout the rest of the episode. Note: this mistake may only apply to the version of the episode that appears on the DVD. In the version of the episode that appears on Disney+, Storm does indeed rip the communicators off her chest. (00:16:20)

Audio problem: Garokk's mouth is wide open when he says "The power of the Earth shall be mine!" (00:17:20)
Savage Land, Strange Heart (2) - S3-E9
Continuity mistake: The edges of the chasm that Jubilee hangs from go from being uneven to straight-lined. (00:13:40)
Savage Land, Strange Heart (2) - S3-E9
Revealing mistake: At various points in the episode, the animation for the flashing red eyes on Garokk's various statues is not synchronized with the physical impression of the eyes on the statues.
Savage Land, Strange Heart (2) - S3-E9
Revealing mistake: When Rogue is saving Jubilee and Wolverine from the stampede of dinosaurs, you can see that the dinosaurs behind them are simply gliding across the screen. (00:04:30)
Savage Land, Strange Heart (2) - S3-E9
Continuity mistake: After Storm destroys the statue of Garokk, his ethereal form petrifies the surrounding area. When it changes to a wider shot, the land is back in its original state. (00:03:30)
Savage Land, Strange Heart (1) - S3-E8
Audio problem: When Wolverine says "On the other hand...", his mouth is wide open for the entire line. (00:20:25)
Savage Land, Strange Heart (1) - S3-E8
Factual error: The amount of rubble that falls onto Sauron would have easily killed him, as his mutant powers do not include the ability to be impervious to heavy damage. (00:18:30)
Savage Land, Strange Heart (1) - S3-E8
Continuity mistake: Wolverine's arms are yellow when Beast catches him. (00:18:05)
Savage Land, Strange Heart (2) - S3-E9
Revealing mistake: When Beast is checking on Storm, his right foot appears under her left armpit despite the fact that she was lying flat on the ground. (00:19:25)
Dark Phoenix (1): Dazzled - S3-E11
Other mistake: When Moira McTaggart asks Jean what happened to her, keep an eye on Banshee. His body slightly stretches horizontally for a split-second. (00:01:15)
Savage Land, Strange Heart (1) - S3-E8
Audio problem: Storm's upper and lower lips are completely separated and her teeth clenched when she says "I am free!" She wouldn't be able to say the words "am" and "free" without touching her lips together. (00:12:20)
Savage Land, Strange Heart (1) - S3-E8
Continuity mistake: When Beast contacts Rogue on her wrist communicator, you can see she is wearing the usual yellow gloves, green sleeves and brown jacket of her uniform. When the shot changes, she is wearing the long-sleeve blue shirt without gloves that she was wearing earlier in the episode. (00:07:40)
Savage Land, Strange Heart (1) - S3-E8
Audio problem: When Sauron says "Ka-Zar, I warned you!", Ka-Zar is actually the one mouthing the line. Note: this mistake may only apply to the DVD version of the episode. Sauron is the one mouthing the line in the Disney+ version of the episode. (00:02:40)
Savage Land, Strange Heart (1) - S3-E8
Continuity mistake: At the very beginning of the episode, Sauron can be seen wearing the necklace of Garokk. Not only is he not wearing the necklace a few shots later, but he isn't even supposed to have the necklace until a few minutes later in the episode when Zaladane gives it to him after he reverts to his human form. (00:01:05 - 00:04:10)
The Phoenix Saga (3): Cry of the Banshee - S3-E5
Other mistake: When the text depicting the episode name appears on screen after the opening credits, it says "The Phoenix Saga Part 2, The Cry of the Banshee." It should read "The Phoenix Saga Part 3, The Cry of the Banshee." Note: this mistake may only apply to the DVD version of the episode. The episode that appears on Disney+ correctly depicts it as "Part III." (00:02:20)
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.
