Other mistake: Rick enters Wendy's room shouting like a madman, and then reaches the bedroom door trying to turn and pull the knob. He bangs the door, calls for Magnum's help, and both then bust the door open. In all that, the guy going through Wendy's underwear and bed sheets is still unfazed and stops what he's doing merely when they almost fall on him. (00:18:00)
Other mistake: Magnum wakes up because Agatha and Higgins are playing with their model planes that loudly buzz in the air. He opens his bedroom window and here they are, by the guesthouse, with a direct view and Higgins waving at him. He then gets out to give them a verbal beating, and he's coming from the main house area. (00:02:15)
