Hi Rotelle, welcome to OSM. May I know the reason behind deleting so many mapped objects? Is it because of your mentioned comment '보안구역' (~"security zone")? As you can see, this area is already mapped as landuse=military : way/301279809

Hi tenziro. I guess in your changeset went something wrong. You moved an intersection node, maybe accidentally? See http://overpass-api.de/achavi/?changeset=45749740

Node: node/1914063432

@Glassman thanks!

Hi ivanxx. May I know the reason behind deleting all your mapped objects? You already wrote that this area is private, but you could use several tags e.g. access=private. See access=private

The name of the way is really "empty place"? way/364000409

Hi JJ KIM, welcome to OSM. I guess in your changeset is something wrong. Why did you delete the service way[1] and mapped two ways without further tags[2]?

[1] way/464445124/history
[2] way/471108992 way/471108991
