1. When you get to a point in the game (Think it is task 27), your game may freeze. You will not be allowed to leave Gryffindor common room and Harry will be doomed to wander the common room forever.
2. Sometimes Harry will walk through a doorway and disappear into the next section, but the camara will not move. If you keep walking it will change but Harry will walk and then appear in a different place. This mainly happens at the entrance to the transifig courtyard.
3. When playing Astronomy, the line you are drawing will jump. However this may be the touch screens fault.
