HUH?  I don't think this is true (the not linked to the routed net in database).

I'm pretty sure they do go away if you do an unroute!  Next time I'm doing
an autoroute, I'll try to verify that.  But, I'm pretty sure they DO go away
after an unroute.  I know they ARE there after the autorouting.  I hit lots
of them when cleaning up.

I wonder if there is a particular step in your work flow that causes them to
get 'un-linked'.
