Hi! It looks like some of the edits in this changeset only has the purpose of replacing a multipolygon (example: https://www.openstreetmap.org/way/1262621355). Please note that adjecant multipolygons sharing ways are valid mapping and replacing them without any other improvements only risk triggerring edit wars. Instead I suggest focusing your time on blank spots on the map, which we have a lot of in Sweden. Happy mapping!
