Can be observed in Queen's Berth, but could be happening in other districts or even in general in every location that has those generic NPCs (or special ones, like Synbel and the two street magicians, see the 2nd screenshot) which are (temporarily) removed for the night or upon leaving the location via one of the "inofficial" exit points (see the 3rd screenshot).

Also worthy to note about this is that highlighting (pressing Tab) with those "detached" vision cones/awareness radii on the screen reduced the framerate and overall performance considerably, in particular for the scenario in the 3rd screenshot. Might be one of the reasons why the Neketaka locations perform so poorly for some people, even on more than capable machines.

Looks like the issue of NPCs not being properly removed (and for some reason leaving behind their vision cones/awareness radii) upon exiting a location could be indeed a general problem.
This is at the main exit of the Vailian Trading Company Headquarters:

On the north exit of Queen's Berth is also one staying circle and cone.

The issue can be observed at entry/exit points to indoor areas as well:
