So the vacuum's momentum changes in the opposite direction of the increased
momentum of the ship. The issue is COM in my mind, not an absolute increase
in momentum. That suggests momentum is not conserved.

Hi,
[snip]
Robin's example of the electric car is different than the EM drive since it
allows the evaluation of the conservation of momentum. The road increases
its momentum in the opposite direction the car does. In the EM case there
is no apparent conservation of momentum--at least I do not know how to
calculate it. Does the entire space time existence change its momentum?
Maybe Robin could identify how momentum is conserved in the EM drive.

See my reply to David. Everyone is making the assumption that a force can
only
act against another object, because that has always been our experience.
This
may be the first tangible experience of a force acting against the vacuum
itself, rather than another object.
If we can warp spacetime, we can also push against it.
