Hi! I fixed typo highway=designated on
osm.org/way/644339156
The ways next to it were highway=path and highway=cycleway. I think path fits best, so I changed it like that:
osm.org/changeset/64554821

Möglicherweise lag es an JOSM, scheint eine total veraltete Version zu sein.

Moin! Was ist denn da schiefgegangen?
highway=3 + footway=Beton an einem Weg mit Länge 0?
osm.org/way/644748882
An der gleichen Stelle ist dann auch noch ein zweiter Weg osm.org/way/644748773

So far only for the first way. Did you find out what went wrong? I am just curious because there might be an error in JOSM. If so, it should be reported and fixed.

Oops, I just noticed that there is a second way on top of the other, so you have to download the area, not a single way.

If you download this way and run the validator JOSM should complain. If it doesn't you probably clicked on the Ignore button.
Try to remove the file validator\ignorederrors.

Any idea what went wrong? I guess you did not intend to produce these nodes.

Thanks for the feedback. There are still a few more:

Yes, OK. Next time watch out for the typo.

The picture shows lamps on the sidewalk and lamps on the major road. Still, they are all rather normal lamps, so I would map them as nodes.

Hi! You changed highway=track to the unusual highway=unsurfaced here
osm.org/way/146708704
Was that intended?

Hi! Please check way osm.org/way/643894897
I think you wanted to draw two single nodes instead?
You should also add the tag lit=yes to the corresponding stretch of osm.org/way/560468809

Hi! I've corrected the typo highway=sevice here:
osm.org/changeset/64475173
DigitalGlobe Premium Imagery shows connections osm.org/way/508120219
Why didn't you map it that way?

Hi! What does highway=model mean?
The bridge is tagged highway=raceway, so I guess this should be used for the whole way?
osm.org/way/643888711

Oops, forgot a link:
osm.org/way/643087705

Hi!
You created some ways with the unusual highway=driveway instead of highway=service + service=driveway.
Was that intended?

Hi!
Your change created a lot of duplicated nodes in osm.org/way/643344602
Similar problem here:
osm.org/way/643369000
Did you disable the corresponding warning in JOSM?

I knew this project. From your comment I got the idea that you visited the place, so the source would be survey and not aerial image.

I think you should also remove the out-aged highway=ford key unless you know an app which still doesn't know ford=yes.

Hi! Would be good if ways like this would be connected to the road network:
osm.org/way/213232382. Why didn't you do that?
