Hmmm, OK! I guess there's something to this mining after all. It's actually a fun grind and found TWO (maybe 3) LTD Core asteroids right next to each other and on the very outside of the ring, so should be very easy to find again. This was literally my first time Core mining, had little feel for how to set the charges perfectly, so I am sure I missed out on a few LTDs, but got 53, and that was with already having a bunch of other stuff I dumped when I found these two rocks.They can be mined over and over by moving 25km (or until you see field "reset") from the rocks and back. I'd still be there, but ran out of time, patience and collector limpets. Sirius is offering $19 Million for them, but I think I can do better. I don't think FDEV messed up mining, I think they just made it a bit harder but as you can see in the picture, two right next to each other! It took me about 45 minutes to find these. Not bad for first core mining trip! Tried to set my first charges on a random core asteroid and it failed, so I was just really learning but think I have it down now! Got as little as 2 LTD once and as much as 9 on one of the rocks on another go. Heading back tomorrow after I sell these and see if I can't fill up! I am much less bitter about mining now. Ha!
