Continuity mistake: The Weasley boys interrupt the exams with their fireworks display. When they fly off, all of the proclamations in their wood frames fall to the floor. The proclamations above the door fall in front of the doorway at Dolores Umbridge's feet. When all of the students run out of the room, all of the proclamations that were in front of the doorway have instantly disappeared.
