Hi, to fix the planet.osm snapshot file, do the following on any command line: cat planet.osm | grep -v "id=\"0\"" > planet-fixed.osm Ciao, Imi. PS Jörg and Steve: Can you fix the files in your upload dirs? PPS: JOSM rev 80 won't load the buggy files anymore. PPPS: Still don't upload any changes made on planet.osm to the OSM server! ;)
