Hi,

I reverted your changeset by changeset https://www.openstreetmap.org/changeset/149016409 due to following reasons:

1. We keep the demolished buildings to avoid that other mappers without on-the-ground knowledge add these "missing" buildings from aerial imagery.

2. Your changeset comment did not explain your changes. OSM is a community project. Community means respect to other users, i.e. properly describing what you did. Just using "akt." is not a meaningful changeset comment. https://wiki.openstreetmap.org/wiki/DE:Good_changeset_comments

Best regards

Michael
