Hello, I don't know what I've committed, but it was finished 1926 according to https://ns.gis-bldam-brandenburg.de/hida4web/view?docId=obj09175668.xml Now it's a marina park (https://marinapark-eberswalde.de/drausicht/) , at the time of my commit it was under construction I think, but now it seems to be finished.

I think this was part of a world heritage border, I'm not sure anymore. Maybe it can be deleted.

Ich hatte auch noch ein paar Darstellungsprobleme mit diesem Stand und hab eine neue Version hochgeladen. Sind die Probleme noch vorhanden? Bei einigen doppelten Nodes könnte es sich um übereinanderliegende Fenster oder Türen handeln, die zusammen auf der Outline liegen.

The area would have the landuse residential, but this is already set on the outer multipolygon.

Sett is the main surface for this area. See here for example: https://vr-easy.com/tour/eberswalde/190821-eberswalde/#pano=17

Merging node/9875379609 with its neighbor will cause OSM2World to crash, so please keep the nodes separate!

Thanks, you're right, I've confused the positions. I'll correct it.
