As I'm exploring planets and come across some of the larger ore pillars, I'm finding that they have an indestructible core. I can clear maybe 2/3 the radius of the mineral, then nothing more. If I put my cursor over it, it will identify the ore correctly - but the mining beam will only cause rocky chunks to fall off without destroying anything, and the ore's durability meter won't decrease.
Is this a glitch? An oversight on the part of the developers? Or is there some enhancement that will let me mine this later? I'm about 7 systems in and haven't found anything that would let me mine it.
