Hi~
Please fill role value. In this case role=outer.
Ohterwise multipolygon does not display as natural=wood. openstreetmap web page display good. But other android app(ie:Osmand) does not display as natural=wood..
OsmAnd app use openstreetmap as base map.
I fixed some area.
Thank you.

Thank you mueschel!
It's my mistake.

bridge:name,bridge:name:en=*=*,bridge:name:ko=*,bridge:name:ko-Latn=*을 그대로 두나요?
아니면 bridge:*로 시작하는 tag를 없애고 name등을 입력하나요?

Because of display wood area gap some zoom level in compiled .map file.
You can edit JOSM.

It is my playground.

Hi~~~
Do not delete name:ko.
name:ko can be referenced by other application programs.
