Humnnn,, Ok. I have observed that, but, what is your definition of "yeild"?When mining now, it doesn't matter whether you are within or above the Optimum yield range. On detonation it suddent jumps to 'above optimum, forecast yield is poor' - BUT - the actual yield is unaffected. In effect Fdev have created a mining exploit.
I should add that now, even if you deliberately set charges way in excess of what's needed, the yield is always 10-14 chunks.
Mine is how many tons of the core material I am able to refine no matter how many fragments were released.
I am finding that the prospector report on the content of the body now actually means something.
14 fragments from a "poor content" yields less tons than 10 fragments from a "High content" body.
