Hi, for your information

I have reverted some of your changesets in the city of Troisdorf, while destroying some intensive 3D-mappings.

My changeset is https://www.openstreetmap.org/changeset/155061935

Please do not make changes on 3D-mapping with iD, because this editor is only for simple tasks, better use JOSM.

Also error messages from iD are not always erros in realitity.

Feel free to connect me
