The House Of No Return - S3-E3
Continuity mistake: The moon changes phases during the night that Chris goes into the house. First it's a full moon, then it's a waxing crescent.
An Old Story - S3-E6
Continuity mistake: When Tom and Jon have grown older the next morning and are talking to Aunt Dalia, she wears a headband with two straps hanging down over her right shoulder, which keep changing position from in front / behind the shoulder.
Revealing mistake: The rocks and tree trunks bend and give way under the weight of Cooper, after he and Fergie are pushed into the cave in the ground.
Continuity mistake: The small twig in Fergie's hair disappears and reappears randomly, after her and Cooper are pushed into the cave in the ground.
Audio problem: When Brian escapes his room and the headmaster with security is checking the rooms, if you look very carefully while the camera is going to Brian's room, you can see the headmaster hitting the door with his hand out, but the sound sounds like it would if he were hitting it with his fist.
Other mistake: Just before the bus comes to pick up Brian, he reads the brochure and says "The Perfect School; why settle for anything less than perfect?" but on the brochure, it says "With perfection, all things are possible."
Continuity mistake: When the security guard enters the room where Brian had hacked the computer, he's out of sight, having hidden in the vent above the room. But he was sitting in the chair just moments before as the guard was opening the door. He couldn't possibly have made it up there in time.
Continuity mistake: The size and shape of the stain on Nicholas' shirt after he falls into the spillage, changes.
Audio problem: Towards the end of the episode just before Grace turns out the lights, Nicholas says "Ugh, now what?" but his lips are not moving at all, even with his head turned.
