If you are at the place where Ron, Malfoy, his friends, and Nevil Longbottom are but they did not appear, use the harrysuperjump code. He will jump past the location. Turn around to see Malfoy, Ron, Nevil and Malfoys friends just standing there but not talking. You may also see Professor Magonigil over by the way to Hagrid's hut. However, do not go in the forest. Use the harrysuperjump code then turn around and she will be standing there, but also will not talk.
