Excuse me if this has already been suggested, but the core is kind of a BIG letdown--monitors? My suggestion is that since minerals have become more valuable as of late maybe a "crystal cave" with MEGA sized crystals could be installed--with removal of monitors (can't get what that is about). At least something more enthralling after all that work to get there than what is there now. Thank you.
there's never been much at the core and it's really easy to get to after getting FSC unlocked (so mega-crystal=OP), also stick with the storyline of unlocking core and repairing skylark
