[OSM-talk] admin_level 4 rendering

[Pierre Béland]

In the relation for Nicaragua (id=287666), there are objects with role subarea.  For example, addition of subarea role for Chontales is redundant with Relation  Chontales (id=2194866). I dont know if this would fix the problem, but you could remove the redundant subarea members from the Nicaragua relation.  Developpers that know how relations are rendered could tell what is the impact of redundant references adding subarea elements to the main relation.

Thank you, Clifford.

I hope I could fix those, by rechecking all the tagging and roles
      ("outer" especially) in the relations. I think this could have
      been the reason. Nevertheless this phenonema of not rendering the
      label of the admin_level=4 regions is happening with all
      regions/departamentos in Nicaragua. Also the ones which are not
      throwing an error by the OSM Inspector [1] Please compare with the
      relations which are subareas of the county's relation [2].
I further added a label to one of the regions' relation [3], using
      the short name for testing purposes, and placed it where no much
      other stuff is around.

Marking the tiles, close to this label node, as "/dirty" to
      refresh them, would not render the region's label... :(
