In future, if you want to change the geometry of a feature already in the database, then please modify it or use the replace geometry plugin, so that its history is preserved. In this case you deleted a building footprint which was added in 2014, and masked its deletion by adding a footprint in its stead. Don't feel too bad about it; I undeleted the footprint to preserve its history.
