Audio problem: When Jeremitt and Catarine are looking for Cindel and Mace, Catarine's mouth barely matches what she's saying. (00:01:20)
Audio problem: When the spider is attacking Wicket, Cindel screams but we can see Cindel when she screams (left hand corner when Wicket is pushed onto the floor) and her mouth isn't moving.
Suggested correction: This isn't a mistake. That's him, under the water in the same pose he was in before he touched the water.
After watching the scene, the mistake is valid. When he's underwater, he's not in the same "pose." That would require him to be upside down and squatting. But that's not the pose we see him in.

We see Mace semi-kneeling and reaching out to touch the water when he vanishes, but his upside-down reflection is still in the exact same calm position even when he's gone, and in the next shot we see Mace under the water right-side up, with his arms reaching up to the surface. This is a valid mistake, the suggested correction is not right.
