Corrected entry: There's a scene where Arnold is talking about saving the neighbourhood, while Helga is on the roof of a building talking to herself. Arnold is in the street, and there's a man in a white tank top standing in front of him. In another shot, the man is standing behind Arnold, and Helga shoots a plunger at his head. Then in the next shot, the man is back in front of Arnold and his head doesn't have the plunger on it anymore.
Corrected entry: In one scene, Grandpa packs up all of Arnold's stuff, but in the scene when Arnold and Gerald have a sleepover, all of Arnold's stuff is back in his room.
Correction: When Arnold finds Grandpa packing Arnold's stuff, at 00:18:40, Grandpa says, "It's only a matter of time now. Everyone else has sold... I have to sell." Then Grandpa tells Arnold about the Tomato Incident. Arnold is convinced he'll track down the historic site document within the next two days, and he'll save the homes and stores when he shows the document to the mayor. At 00:21:10, Arnold tells Grandpa not to sell the boarding house, and Grandpa replies, "You're a bold kid, I'm with you all the way." So while offscreen, Arnold and Grandpa unpack Arnold's stuff. It's at 00:33:25 that we next see Arnold's room when Gerald is sleeping over that night. The continuity is not problematic.
Correction: No changes occur between shots. While Helga is alone on the roof professing her love for Arnold, first she has a slingshot and this bald man stands in the crowd in front of Arnold. Eight shots later, Helga has a crossbow loaded with a suction cup arrow, then lines up the scope's crosshairs on the bald man standing behind Arnold (he had plenty of time to move during the eight shots offscreen), at 00:06:05. Next shot, the suction cup arrow lands on the bald man's head, and he's still standing behind Arnold. Then three shots later, while this man was offscreen again, he has removed the suction cup arrow that was stuck on his head and rejoined the crowd gathered in front of Arnold (well, who can blame him, some nut landed a toy arrow on his head while he stood behind Arnold).
