After upgrade to 11.5.2 Network Atlas no longer has access to devices not shown on map. Previously a city folder had all devices which you could drag to the map.
I had something similar to that in Network Atlas as well as a couple of other issues with NPM not being able to list resources. Applying the Orion Platform v2015.1.2-HotFix2 fixed the problems.
