Continuity mistake: When Dr. Bohlson is cutting through the bandages around Carly's eyes, there is an audible tear, but when he stops cutting and steps away, the bandages are completely intact. (00:11:10)
Plot hole: After Beast and Dr. Bohlson leave Carly's room, they briefly chat in the hallway just outside the door for less than 15 seconds in real time, and then discover that in that brief time frame, the Friends of Humanity abducted Carly from her second-story room via the window, managed to incapacitate the nurse, security guard and Carly's father, toss around furniture and spray paint "For Humanity" on one of the walls, all without any of the victims making a sound or the Friends of Humanity making a sound themselves. The Friends of Humanity aren't ninjas, rather they are shown to be somewhat bumbling, so there's no way they could have done all that as quickly and quietly as shown. (00:12:30)

When Wolverine tells Creed to let her go, they are suddenly right next to a wall on Carly's right. Then when Creed is pointing the gun at Wolverine and for the remainder of the scene, Carly is suddenly facing the door Wolverine came through. (00:15:35 - 00:17:50)
Continuity mistake: When Carly is telling Graydon Creed to leave her alone, her head is tilted towards her right shoulder. When the shot changes, she is facing straight. (00:15:57)
Continuity mistake: When Wolverine interrupts the two men playing poker, you can see there are only cards and chips on the table. When the shot changes, a mug has appeared next to the white man's left elbow. (00:16:28)

Continuity mistake: When Wolverine is asking Graydon Creed if he looks familiar to him, his cuspids are very long and sharp. Later when Wolverine is sneering at Creed during his breakdown, you can see his cuspids are now flat and not as long. (00:17:29 - 00:19:36)

Mojovision - S2-E11
Audio problem: When Mojo is twirling around in a circle and saying "Am I standing?" to Major Domo, you can see his mouth is wide open for the entire line. (00:04:10)

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.
