 This is in relation to node-based cycle and hiking networks, where the
 endpoints rather than the connecting routes have refs. Potlatch2 normally
 lists these routes with a name based on the refs of the endpoints.
 Sometimes this fails, however.

 An example:

 http://www.openstreetmap.org/?lat=50.86198&lon=4.681851&zoom=18&layers=M

 This is the intersection containing node 75 (OID 872014261), from which
 two nameless rcn relations go on to nodes 73 and 74.

 If I start Potlatch2 zoomed in, both routes are given the wrong name "-75"
 and "-60". If I zoom out to the point that node 74 is included in the
 loaded data, the first route's name is corrected to "74-75". I assume this
 is an inherent limitation, in that the endpoint can't be shown without
 first loading it?

 This being the case, "-60" for relation 6115 is still incorrect, as this
 route actually ends on node 75. It seems that Potlatch2 is somehow
 detecting the rwn node 60 (OID 16652149) as the endpoint of the rcn route,
 despite that it's in the middle and that the route is marked as an "rcn"
 route. Any idea what might be causing this, and if it's a data or a
 software error?

 Cheers,
 Jw
