What happens if your orders get changed after your HHG pickup is scheduled?

If HHG is scheduled, but not picked up, no worries. Go to movement office, let them know. They can still pick up, just won't route for delivery.

If HHG have been picked up, still no worries. Go to movement office let them know, and HHG will be rerouted.

And obviously, get your orders ASAP, and get them over to the movement office.

Simple, go to movement office with a copy of your rescinded orders and they will put a hold on your shipment and schedule it for return to your last post or divert it to your new assignment.
