if you relog or jump out of the system it will eventually spam the scouts
I've jumped out and back again, but it was still spawning a sensor. May be exploited to have BGS shift at stations with blackmarket?
I've also somehow managed to scoop one and destroy it at the same time. It was 30% hulls left and I was near 40 m/s, got in the inventory but I still had two materials and heard the destruction sound. Maybe it could be reproduced.
