I should mention that if I then re-export again, back to Freerouter, it does not show the
same 3 "incompletes" (which are Freerouter's ratsnests).

This suggests:

1) that KiCad and Freerouter have a difference of opinion on whether the 3 nets are
connected.  Freerouter thinks they ARE connected.

2) that the "back import" could not have damaged the 3 nets to the point of
unconnectivity, since the re-export goes back over to Freerouter fine.
