Have you tried playing standard career mode and not science mode? Thats how i got mine to work. I myself have 2 problems. The 1st one and im not sure how to test it is when i research something in the R&D center its doesnt progress to the next node until I leave the R&D center then come back, any ideas? Also my radiators are really busted, it may be because of tweakscale and Interstellar having issues im not sure, but the Huge radiator only disperses 89 MW of power on 100% scale, on 140% it does 382 MW (this is on duel sym so I guess 2 disperse that much) any ideas?
