Hello RKhabib, 

You deleted a large number of objects in this changeset and then subsequently added new ones in https://www.openstreetmap.org/changeset/171992744

However there are some issues with that changeset. Namely:
* There is no source listed
* All buildings are part of a gigantic unneccecary 4213 member relation
* The individual building outlines all have the nonsensical tag `Id=0`
* You have not adjusted any of the previously mapped roads, which now overlap with the buildings.

Is this some sort of import? if so, what is the source of this import and can we use their data?

Best regard, 
Taya Snijder
