 Every few weeks I find a destroyed multipolygon relation in my mapping
 area, of which segements are deleted so that mapnik cannot render them
 anymore. The associated editor is always potlach2. And the responsible
 mappers are always unaware of the damage they do. This is because potlach2
 doesn't make clear enough that a way is part of a multipolygon relation
 and doesn't give proper warnings when a multipolygon is invalidated. JOSM
 for instance performs a validity check when uploading.

 Please include clear warnings in potlach2 to alert mappers if they are
 about to invalidate a multipolygon or show it much clearer if a way's role
 is to be part of a multipolygon.

 Thank you!
