I added this changeset over a day ago (a natural reserve boundary). The ways are definitely in the database and tagged correctly: boundary=national_park. However, the natural reserve is not rendering on the OSM slippy map.

The changeset was created from an ESRI Shapefile imported using JOSM, as described in the wiki. Is the multipolygon constructed incorrectly? What am I doing wrong here? I'd like to add many unmapped conservation areas like this.

EDIT: After these changes by another user, it's starting to render at some zoom levels. I still don't understand what I did wrong, though. What was broken in my initial changeset?

It looks like it was edited to version 2 about 6 hours ago and renders now, however I suspect the role for this way should be inner, rather than outer. Edit: I'm half asleep. Clearly it does have role "inner" already.

Yes, it's starting to render at some zoom levels. What problem did the edit resolve though? How can I avoid this in the future?

I looked at the history of the relation and couldn't see anything obviously wrong. The edit seems to have been to use existing ways where possible rather than just reusing their nodes. It may be you had old tiles cached locally so just weren't seeing the render maybe?

At least at zoom level 13 it renders for me http://www.openstreetmap.org/#map=13/45.3521/136.5127

You may need to reload.

It's starting to render at some zoom levels after a fix by another user (updated question). Not sure what they did and still want to understand what my mistake was.

If you were to have similar problems in the future, this website http://analyser.openstreetmap.fr/ will analyse a multipolygon (or any relation) for you and tell you if there are any obvious errors, like openings ("ouvertures") or self-intersections.
