I merged the OSM files of Belgium, Zeeland (Netherlands) and Nord Pas de Calais (France). When I started importing Belgium and the Zeeland part of the Netherlands the graph-creating went well. When I added Nord Pas de Calais (and now the whole of France) I’m getting an error with OSM nodes that are duplicates?
Caused by: java.lang.IllegalStateException: Unknown node type: -428454, or coordinates already set. Possibly duplicate OSM node ID: 268180075
