RE: https://www.openstreetmap.org/relation/8481981 (and others)

Thanks for helping map golf courses. There are some problems with your edits however and your mapping process needs to be fixed going forward so you don't continue to step on the efforts of others. For starters, you should read the following wiki: https://wiki.openstreetmap.org/wiki/Keep_the_history on how important it is to *not* delete map elements when you should be modifying them instead. You break multipolygon relations when you delete something like a fairway that belongs to a relation only to redraw it and not properly add it back to the existing relation. You should also read the golf_course wiki (https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dgolf_course#Common_mapping_pitfalls) and the general wiki on how to properly work with multipolygons (https://wiki.openstreetmap.org/wiki/Relation:multipolygon#iD). Thanks.
