Misaligned nodes in GPSmapedit 1.1.73.2

[Seldom]

Anybody here making routable maps besides me? 

Also posted on Map Authors forum:

I've used Global Mapper 13 to substitute some road data into an existing PFM
map. When I Verify Map in GPSmapedit after building a routing graph I'm getting
around 300 Misaligned node errors and duplicated node errors. I've been fixing
these manually in GPSmapedit, but it's time consuming (say 30 seconds per
error). The MP file is about 4.6MB, covers 1 degree, and contains 13,000
routing nodes.

Anybody know of a fix (or speedup) for this process?
