I don’t blame you for the bad changeset, you know.  It has already been fixed and the courtyard you are referring to is now correctly mapped.
I understand it is a difficult case for you because this is one (rare) occurrence where we must strive to keep OSM data in sync with official UrbIS data for building outlines despite it looks like the real building is shorter; that explains why it requires some complicated piling up of building and building:part objects.
