Thanks for helping map golf courses. There are some serious problems with your edits however and your mapping needs to be fixed going forward so you don't continue to step on the efforts of others. For starters, 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 updating them instead. You have been breaking multipolygon relations when you do this. 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). Until you understand these issues, please refrain from modifying other mapper's work. Thanks. If you have any questions, please reach out and we'll gladly help you.
