If you stand about half way between two big poles and zoom in closely, the cable (wire) just disappears (is not rendered, invisible). Interesting is that if you walk closer to the pole it will appear again. I guess it's the poles unloading or something...
the cable shows normally
from far away
the cable disappears
same place, zoomed in
the cable reappears again when near the pole
same zoom level, moved to the pole
Sorry if it feels stupid to report, but I'm kind of an OCD...
