Still on the map, but nothing to aquire here - like radio etc.?
Maybe you can loot these Field Radios from beacons only once, like the adrenaline stims you can find in the world. Normally beacons once destroyed do not re-spawn. But some do, which might be a glitch.
I wish they all would respawn, or at least 21 spread out over the regions. It would make the game world a lot more pleasant because beacons are always guarded by machines.
Yes! I agree! (too short: right!)
