Calling TeleportTo() on an empty mutator_zone_device causes verse to crash

Make sure that you do not assign a value to MyZone in the editor (leave it as None)

Not especially related to mutator_zone_device, allow me

• Safe GetTransform() calls and general null checking.
• Critical - GetTransform() error shuts down a lot of verse devices.
