I'm not sure how well FDev can come out of this:
a) they don't intend us to brought force this, there are clues, but we are all just too stupid to have found them and figured them out.
b) they don't intend us to brought force this, there were clues, but someone at FDev screwed up and they didn't get released and/or bugged.
c) they don't intend us to brought force this, they expect'd us to realise it's an almost impossible task, as we have NO TOOLs to search a planet, we should just wait for FDev to throw us another bone - when they have figured out what type of bone to throw us.
d) they do intend for us to wasted our precious gaming time looking for a slight different beige smudge on a beige landscape stretched over a million km2 of planetary surfaces.
Frankly none of these options are fun game play and none of them make FDev look good. - Worse they make us look bad for assuming it's a,b or d and wasting our precious gaming time.
