Good idea to create a map. Maybe in the future even one with all the collectables and guaranteed weapon locations on it as well.
I have not seen a single beacon respawn since I started the game 2 months ago.
But remember those floating lights that fade away when you get closer? I’m now 100% sure those are from the beacons.
Here you can even see the light while the beacon is still intact (to the top left of the crosshair):
And here is the light from the beacon on your map:
It’s slightly off from your icon location and I could not find another light there in the bush. From an early save it seems they are both there at the same time:
I also checked several of the locations from your map and the floating lights are all there at the spots where the beacons should be (although they are all slightly off).
Even the very first beacon we all are forced to encounter has that light at that location (slightly less visible because of twilight):
O yeah … that “Loc” in the north of your map is actually “Beredskapsförråd 111”, as I found out when re-investigating that snow in bunker bug.
