Both of these Argentinian provinces don't show up on the map, but they seem to be fine in OSM. osm2pgsql problem, or just some data hickup that would fix itself within two days?
Seems to work now. When I tried to display these objects via geoline service some time ago then border between Q44756 and Q44829 had some gaps. Around these gaps, I note that someone fixed a duplicate node for border segment w498585495 a couple of weeks ago. Maybe that was the problem.
