It looks like one of the node drags here made a dozen or so relations invalid, including "10709165 | Monkstown Parish".  I've dragged that back in https://www.openstreetmap.org/changeset/172414229 so that the relation is now https://www.openstreetmap.org/relation/10709165#map=19/53.258073/-6.197441 , as opposed to self-intersecting (which made it an invalid polygon).  This also affected "10709158 | Kilternan Parish", "13062149 | Glencullen ED 1901", "13061513 | Ballybrack ED 1901", "12491333 | Ballybrack ED", "12430312 | Glencullen ED", "4608457 | Tully", "2236209 | Kilgobbin" and possibly some others.
You can use Josm's relation validator to check relations (see https://www.openstreetmap.org/user/SomeoneElse/diary/406398 ) even if you don't edit relations in Josm.
