Yes, Ive completed the skyscale collections as well and cannot craft the treats. I have the recipe and all the matts. Progress bar fills up while crafting them but no matts are consumed and I don't get the treats. This is pretty lame as I'm trying to craft the treats to help my son finish the collection. Hes only 8 and has a hard time with the jump puzzles. Rather than do them all over again myself, i'd rather just make him the treats as i have loads of charged quartz stockpiled anyways.
