My first attempt at a multipolygon forest (a polygon with a hole in it) looks (to me) OK in the editor (looking both in iD and JOSM), but the final rendered map doesn't appear as a forest and its boundary pops unevenly into view depending on the zoom level. What obvious thing have I failed to do? |

The forest looks fine for me. It could be that the rendering servers for your region just haven't caught up yet. You can also try clearing your browser's cache, in case you had looked at the area before you edited and the browser is still using some of the old tiles. |

Agreed the re-rendering sometimes takes a while to complete at all zoom levels, this might account for the intermittency. A couple of other points on the multipolygon. The inner polygon is only tagged area=yes, the fact that it is an enclosing polygon means area=yes is not needed, that's implied. But the area does need a descriptive tag, perhaps landuse=meadow or landuse=grass. 1
To hopefully avoid confusion: The inner polygon doesn't need any tags at all, neither area=yes nor anything else. You can of course also map what's inside that hole, and if the entire area is filled with a single thing, you may feel it's convenient to re-use the inner ring of the multipolygon to represent that thing. But ultimately, that's not any different from mapping something like grass outside the forest, it has nothing to do with the relation. (Just pointing that out because it's a common misunderstanding that the tags on multipolygon inner members have some special meaning.)
