not sure if it is real, i was just fixing geometry errors

OSM inspector highlights errors on the map. http://tools.geofabrik.de/osmi/
I have been removing ways with a single node, which are geometry errors.

New Roads added in Nardaran are disconnected and do not route:

Are these individual buildings? I think they just painted the roofs for effect.
If you do want them as individual buildings, please tag them with areas (not lines) and add the tag "building".

osm.org/node/1891046001
Has fixme flag = yes.
What needs fixing?

osm.org/way/315178137
http://tools.geofabrik.de/osmi/
missing tag: Road? Path?

This way:
osm.org/way/318707715
What is it? Road? footpath?

Agreed, I had it noted as a bypass, but checking the pictures it is only white lines.
I have deleted the bypass

It was a syntax correction.
"40mph" to "40 mph" as per wiki.
I am checking all speed cameras globally via:
