vielen, vielen Dank, ich weiss nicht warum habe ich das so kaputt gemacht!

Naja, mein hessisch ischt nix so gut.
Ich weiss nicht, was ich bei Gravenbruch falsch gemacht hätte, ich habe höchstens die Grenze gesplittet.

Mit area es wäre eine gute Lösung, man muss nur die Grenzen irgendwie bekommen...

Yes, sorry for that. I've had this one open and JOSM merged two unrelated things :(

District boundary is now drawn in the (misnamed) changeset osm.org/changeset/41651634

Well, I have restored it for now. It will take a while to get the boundaries right....

working on it... the problem is:
- Offenbach is not fully covered by official districts (vague "downtown" is not there)
- Nominatim picks the nearest suburb and adds it to all street names etc.

I found some district boundaries, and yes, mapping a real boundary would be a way better solution.
