Tintin in Tibet: Part 2 - S2-E7
Other mistake: Haddock becomes exhausted and sits down. Tintin points out he'll freeze. Watch the two horizontal strips along the middle of his jacket. They are yellow for a few frames, then they go to blue for a few frames. Then if you look super carefully, you'll see that the two straps vanish from shot for a quick frame. Then they reappear.

Other mistake: As Tintin, Haddock and Tharkey set up camp, Tintin gets blown back by the tent. Tintin starts running as he is pulled by the tent and trips once he lets go. You'll notice that there is a huge skid mark from his landing on the ground before he does so. (00:28:30)

Other mistake: When Tintin is running as he is being dragged by the tent, he leaves no footprints in the snow. (00:28:25)
Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
