Hi, I currently try to get ride of this thousands of warnings about "WARNING (MultiPolygonRelation): 71200001.osm.pbf: Cannot join the following ways to closed polygons..." So I have the following line in my logging.properties file: uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation=SEVERE For all other cases this works fine, somehow only for the MultiPolygonRelation.class it seems to be ignored? Even if I remove that line, it's still printed. And yes, I'm sure I don't have it a second time in my file. Any idea what I can make wrong?
