Hi Marko,

Yes, those warnings are not ideal - I will take a look and see if I can
remove the dups. Also, I nearly added the download URL the other day
but I was too lazy, I'll do it now!

The thing about automatically converting stuff is that you have to be
100% sure that it's wrong otherwise you just make the problem worse.

I guess the triangle shaped flares could be fixed automatically but
when I go and edit the OSM data where the flare road errors are, I am
finding all sorts of bad stuff and fixing that as well so it has a
double benefit.
