Some of the promethium nuggets I find in deposits cannot be mined. Even some small ones never break up and get collected. Is this a bug? There is still no indicator on the depletion amount of the ore. Thank you!
Have you the Ore Scanner equiped? I think this one is necessary to recognize the ore in the deposit, without this device you are almost blind as to where you must mine. If I have depleted a deposit (in my case: Neodynium) it will now show 0% in the Registry, and no more icon in the planet map.
