Hat das einen Grund, warum Du das Äußere Polygon way/158529665 gelöscht und damite das Multipolygon https://tools.geofabrik.de/osmi/?view=areas&lon=7.91286&lat=53.64590&zoom=14&baselayer=Geofabrik%20Standard&opacity=0.95&overlays=duplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways%2Cduplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways verstümmelt hast? Ähnliches hattest Du bereits mit der MP-Relation https://osm.mapki.com/history/relation/2123680 gemacht.

Please do not add new highways (way/1323243005) where one already exists. Adjust the tags on existing ways instead. Do not add fake landuses to indicate track properties. Add suitable properties (mtb:scale=*) to the corresponding road section instead.

War das Absicht, dass Du den äußeren Ring https://overpass-turbo.eu/s/1UYO des Multipolygons https://overpass-turbo.eu/s/1UYR gelöscht hast?

Is there a reason to change relation type=superroute to type=boundary?

Was ist das für eine Art von landuse? Ist das irgendwo dokumentiert?

Wo ist hier der Einfluss von Wasser (siehe relation/18292107)?:

What I found were two incomplete multipolygons and two untagged ways. So much for the small error.

I didn't delete any of your work, nor did I add a single new node.

What I did was that I added the members of one multipolygon to the other. I then deleted this multipolygon because it had become superfluous. I combined one of the untagged ways with another one, which deleted it. I completed the remaining multipolygon with the remaining untagged way and added the necessary tags for the Lac Vital.

Wird das mal zu Ende gebracht:

Warum wird jetzt eine Buslinie (type=route) plötzlich zu einer Grenze (type=boundary)?

Ein Multipolygon definiert eine Fläche, wobei die Flächen, die von den inner-Polygonen gebildet werden, von der Multipolygonfläche ausgeschlossen sind. Ich nehme an, das war von dir nicht so gemeint, dass alle die inner-Flächen nicht zum Golfplatz gehören.

Bitte achte besser auf Multipolygonflächen, hatte es gerade repariert:
