Hi miluethi,
your recent changesets have created a lot of errors in the OSM database regarding self intersecting ways:

Most probably you selected a bunch of buildings and just pressed "q" without checking the results.

May be you like to use the internal validator of JOSM before you upload to avoid such errors:

An other side effect of your edit is that the shape of the affected buildings no longer matches the reality. This is not only valid for buildings that originally had a circular shape.

Can you please fix this?
Kind regards
Guido
