I would assume it affects how much water you get from the Aero-evaporator CBM (or whatever it’s called - the one that makes water from the air for 200 power). Once in a while, you get none, sometimes you get one, often you get 2, occasionally you get more.
Also, in the latest experimental, has someone tweaked the bloody huge boomers? I’m in full survivor gear, and they’re glowing me about half the time (or more), and it’s lasting MUCH MUCH MUCH longer than before.
Oh, and explosions are still crazy big, but they seem to be less “nuke every single item out of existence the moment you touch it” than they were, so that loot isn’t just auto-destroyed all the bloody time, and/but corpses aren’t, either (which is nice… and harder, of course).
