Other mistake: When reloading the G3 rifle you can see that there aren't any bullets in the new magazine. Also, when firing the G36 rifle the amount of bullets in the glass magazine won't reduce visually.
Factual error: The design of Hammersmith Bridge is completely wrong as one tower is taller than the other - they should both be the same height.
Bug: If you try and offer Captain Dread something that he doesn't want, he turns around and faces Guybrush to decline the offer. If you then try and talk to him however, Dread's face appears on the back of his head, and he somehow then turns around again to face Guybrush.
Bug: If you stand in front of a bug or a fish and press start right after swinging a bottle at it, you can put another item in the bottle's place and turn it into another bottle. When this happens, the erased item cannot be recovered, and the new bottle will retain the limitations of the original item (for example, turning the Claim Check into a bottle will still be unable to be used by Young Link.).
Bug: Any time you pass through a portal keep holding the movement button in the same direction, sometimes when you are finished going through Spyro will move around but there will be no animation of him doing so. He just glides along on the ground.
Continuity mistake: At the end of this game, Trogdor announces that he's invincible, and demonstrates that he is at least immune to swords; but in the actual game "Trogdor" he is easily killed with a sword.
Other mistake: In the first case, when Phoenix is in the lobby, Maya hands him a document. The specifics say that it was received from "Maya Fay." However, at this point in the game, Phoenix doesn't recognize her (because he has amnesia), so there is no way he'd know it was from "Maya Fay."
Plot hole: When Umbride is about to use the Cruciatus curse to interrogate Harry towards the end of the story missions, Herminone says "Tell her. It's not worth another student dying." No students had died (not since Cedric Diggory anyway), were threatened with death or were in any kind of fatal situation yet. What is she on about?
Suggested correction: Exactly what she means. Cedric Diggory is dead so it's nothing worth Harry to die over.
Continuity mistake: When you use the Predator's vocal mimicry ability the Predator says lines from cutscenes you haven't seen yet as well as lines from scenes in which the Predator wasn't present to record them.
Bug: There is a glitch where you can walk in the gray/green space that the place was created in any playground. You need a friend. You click on their name, then click "Whisper" and say "Can you teleport to me?" When you see the whisper that "(insert toon name here) is coming to visit you", wait a little, then go through the door. They will teleport near you, and outside of the door (and in the Grayspace). Then, if it worked, you can teleport to them and be in it too. This helps you get to the pillow glitch, which is accomplished by running around Donald's Dreamland in the Gray, and getting to the pillow. Then just jump.
Plot hole: When Tails is flying towards Prison Island for the first time, he spots Amy on the island surrounded by enemies after mistaking Shadow for Sonic. There is no explanation given for how Amy arrives on such a guarded and fortified island. When Sonic asks her later, she says that she hitched a ride with Tails in his plane, but she couldn't have, as Tails spotted her on the island as he was flying in.
Suggested correction: Amy was talking about how she made it inside the prison, not how she made it to the island. There being no explanation of how she made it to the island isn't really a plot hole either way. It's just something that is never explained.
Other mistake: If you use an entrance that shows a wrestler's teeth on The Rock you will see that he has no teeth.
Continuity mistake: In the European version of the game, after beating the Normal Campaign, you can go to the Battle Maps shop and purchase Black Hole CO Zak, however when Hachi asks you to confirm the purchase, he is called Koal, not Zak. This is the US name, which they forgot to change.
Continuity mistake: In the scene where the Prince (wraith) jumps across the gap in the clock tower he gets knocked out by a Brute, but when the real Prince jumps the same gap, the Brute smashes through a wall even though he was already out of the wall when the wraith was knocked out.
Other mistake: At one point on talk radio show Chatterbox, Maria (Salvatore's girlfriend) calls up to ask Lazlow for romantic advice. In her call, she describes the events that occur in the game involving Salvatore betraying the game's protagonist and how Maria is falling for him. This conversation can be heard on the radio before the events have actually happened in the storyline.
Factual error: With the special key, Claire can alter her clothes to a costume that is equipped with a Colt Single Action Army. But still she can fill it with 9mm parabellum which would be impossible.
Revealing mistake: When fighting Gohma on Dragon Roost Island, when Link uses the grappling hook to grapple Valoo's tail, some of the rope goes through the tail as it wraps around.
Bug: On custom stages, if you have the springs set up, there is a glitch with them that occurs with Meta Knight's final smash. If he is in the middle of using his final smash, and any other player happens to touch a spring during that, they instantly freeze and are unable to move until the final smash is over. And it seems to somehow amplify the effects of the smash on the frozen players.
Character mistake: In the opening cinematic (before you press start), the group hears a witch crying, and Bill and Zoey go to investigate. Louis and Francis stay outside to keep watch. When, in the dark, Bill and Zoey approach the witch, Zoey puts her flashlight on the witch and Bill immediately says, "lights off!" Now here is the confusion - Bill knows it's a witch, so shouldn't he know what they sound like and not enter the room in the first place?
