Hi Gerd, I was very afraid you would ask for an example! I'm 100% sure it's OK on OSM. JOSM validation would protest! Immediately! Examples are very rare AND are always Resolved. If I find one piece of my own Garbage tomorrow I will resolve the same day. The next day I will conclude that it has indeed been solved. By exception: I will wait for OpenFietsMap to see if it has the same issue. In case I do wait, the issue is always confirmed by OpenFietsMap. Also: if I resolve, I will not (no need) Connect or JOIN. My only actions: move the connecting node (and sometimes: delete some nodes). I could have a look at my Changeset Comments. And than... revert my solution? Create Errors deliberately? Lol, please don't tell anyone; -)) Back in memory lane: I now do remember one issue. But also: that was one year ago! The Netherlands, Wassenaar? Roundabout? Can I search my own Changeset Comments? But also: you do not ignore my issue. So next time I do find one, I will NOT resolve and send you the link immediately. Next: I will read your "Distorted-lines". But be prepared for ignore modus: I might not respond anymore because I cannot find an example. Now I understand why it took a few years before I posted this. If it is not reproducible, a solution is almost impossible. / Eric (AnkEric) -- Sent from: http://gis.19327.n8.nabble.com/Mkgmap-Development-f5324443.html
