Just spent 15 min watching fast moving dar heading to strats, as no bases where flashing I guessed he was threading his way through the radar rings. I lifted to cover the city and intercept the con.
While flying I keeped map open to check movement of the dar. It soon became apparent that something was not right as the dar was moving across sector lines that had tight overlapping dar rings that should have flashed the base and given a dot on radar.
You can see what I mean on the attached images.
This happen for over 4 different sector lines I watched.
Unsure whats going
