I think they nerfed the ql 10 Concrete Cushions... they don't seem to be coming up as mission rewards or the item to be found anymore.
I was playing an alt and at lvl 10 now I've stopped to try to get cushions (like all sensible rubikans do), but it's now 200 rolls from clicksaver without a hit.
I could just be very very unlucky, but I dunno... this would be a poor change if it's really in place .
