They've got a relation of admin_level=8 around them. Maybe this relation also needs to be made up of only ways with admin_level=8. We currently have some borders that have odd intersections (mainly found and fixed them on the coastlines so far). Those issues look something like this (exageration): | | A | + / \ B / \ C / \ -+---+- D E F Then we have relations: admin_level=8: D, E, F admin_level=9/1: A, B, D admin_level=9/2: A, C, F And of course there are even more weird versions of it. If now someone tries to correct that, he might remove E and join D+B and C+F ... potentially leading to incorrectly tagged admin_level. Additionally some JOSM versions had a problem with joining two members of the same relation ... by default (and anything else being virtually invisible initially) this produced duplicate relation membership.

And maybe add it to the relation ... I've seen it somewhere ... or was it for the capital? Additionally you never know who might need it. But let's see what'll be the result.

At least I also do not yet have a good idea. My first idea was that maybe it does not like relations, and wants to use simple ways? But I assume Kärdla was also defined as relation? Actually Kärdla seems to be only city name which is selectable there properly, I could not find any other? I traced a bit JSON data what is returned by nominatim. It seems that for other cities it gives point, not boundary region. Maybe there is no centroid point for Kärdla, and there is for other cities and this confuses the Nominatim? Solution/test: remove centroid points for other cities too. Or does anyone needs them once you have the boundary polygon (relation) present? Sounds like redundant data for me.
