Night of the Sentinels: Part 2 - S1-E2
Continuity mistake: At the end of the previous episode, Rogue says to Cyclops "You look nervous as a long-tailed cat in a room full of rocking chairs," to which he responds, "I just wish I knew what was happening in there." Cyclops then immediately looks to his right and sees military vehicles approaching and says "We've got trouble." At the beginning of this episode, the same scene is shown again, only this time Gambit says "If that was me in there you wouldn't have to worry" before the military vehicles are shown to be arriving.

Character mistake: When Beast is uploading the virus to delete all the mutant files from the computer, Storm destroys the monitor with a bolt of lightning and says they have run out of time. Destroying the monitor wouldn't magically erase the files. While she may not know that, Beast definitely would, so at the least, he should have asked her to destroy the computer tower and hard drive as well. (00:06:13)
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.
