If the Mover is deleted, nothing should actually happen. The last known morph state remains as it is and is not changed anymore. "update_morph" is no longer called.

But: Actually, there should be an error message, because "move_actor.WorldDisplacement()" cannot be executed by Poser anymore (the "move_actor" is gone).

The script here is not intended for production. In order to use the method in a meaningful way, a little bit more work is needed around it.
