So I came back to the game after a while and was looking to fuel back up my carrier but when I go to mine the PWA doesn't seem to pick up much, and when it does after I fly to the rock the glow disappears when I pulse again and there isn't actually anything in it. It only seems to work on core asteroids now. Did they remove surface/subserface deposits on non-core asteroids or am I forgetting something and doing it wrong.
