I didn't see anything on a quick scan of the data all the way south to
my destination. All nodes were connected. I usually rely on KeepRight to
flag errors in the data and nothing is reported as far as I can tell. No
tunnels, nothing, just a straight road to destination. MapSource doesn't
seem to have the issue which is strange.

I will try it tomorrow if I have time.

Thanks. I am out of ideas given that MapSource works.
