It means exactly what it says:
An attempt was made to use the actor's location while it is not in the world. Either it has not yet been inserted, or it has been removed.
Any time you try to call a method that requires that the actor be in the world, but the actor is not, you will get this message. Look at line 32 in your Mouse class. It tries to use 'getoneIntersectingObject' there. For some reason, the actor was not in the world when the execution of this line was attempted.
