* Moves the loc assignment for null doMove target locations to before exited() is called, making it consistent with other uses of the proc, and fixing a harddel caused by deleting something inside of an open storage component. The component assumes that the removed object has already exited its contents, and so readds it to the screen, causing PAIN
