Hat schon jemand repariert:
changeset/135789364
changeset/135790754
Durch Auftrennung des ways way/106087603 war das Multipolygon relation/13650356 kaputt

Bitte reparieren 13650356

Was denn nun?
Wohngebiet relation/15812328#map=16/48.9260/9.4254
oder Brachfläche relation/15812327

Bitte verstümmelte Grenze berichtigen:

This and the following changesets
changeset/134978467 and
changeset/135062348 did not create intersections, they are part of fixing the issues caused by changeset
changeset/134651394 . The fix now should be completed.

Maybe you did not add new ways but you moved a lot of way nodes which changed way geometry and caused intersections. Having reversed your node shifts should have fixed the intersections by now.

Bitte Rollen berichtigen: relation/15724817

Der Relationstyp multipolygon dient der Kartierung von Flächen, die nicht als einfaches Polygon (=geschlossener Ring) dargetellt werden können, sondern dafür mehrere Polygone benötigen. Die Zusammenfassung von einzelnen Mauerabschnitten ist kein Multipolygon.

Verschobene Knoten revertiert: changeset/135056188

That cannot be correct:

Ist die Datenlizenz für die Verwendung in OSM inzwischen geklärt? Siehe https://community.openstreetmap.org/t/datenlizenz-deutschland-rheinland-pfalz/74775

Davon abgesehen boundary=protected_area => Relation type=boundary

Rollen überprüfen!

Warum legst Du hier eine völlg neue Relation https://osm.mapki.com/history/relation/15411840 an wo doch schon eine https://osm.mapki.com/history/relation/2511819 existiert? Anstatt die bestehende schrittweise zu löschen und durch die neue zu ersetzen und damit die ursprüngliche Historie zu tilgen, solltet Du besser die bestehende Relation weiterentwickeln.

bittte etwas mehr Sorgfalt: https://tools.geofabrik.de/osmi/?view=areas&lon=6.84422&lat=50.47781&zoom=16&baselayer=Geofabrik%20Standard&opacity=0.95&overlays=intersection%2Cintersecting_segments%2Cways

One feature - oneOSM object (osm.wiki/One_feature,_one_OSM_element):
cycleway way/1149145825#map=17/46.98683/6.91676 and way/1149145824#map=16/46.9850/6.9129 already exist tagged as cycleway=lane on primary highway. Please adjust.

Aber nicht in der von mir verlinkten relation/15489316. Siehe auch Versionshistorie:
https://osm.mapki.com/history/relation/15489316

Aber was hat das mit einer Grenze (type=boundary) zu tun?

Was willt Du mit dieser Relation darstellen: relation/15489316 ?

Was willt Du damit bezwecken, eine existierende (https://osm.mapki.com/history/relation/1741732) Relation nochmal anzulegen (https://osm.mapki.com/history/relation/15426866) und die alte zu verstümmeln: relation/1741732#map=16/48.8181/15.2644
