I was very lucky and got a Purple Innoculator Schematic drop the other day so set about crafting a few.
Got one I really liked, 1 Red, 2 Multi and a Green slot, but was waiting for another item to boost Warfare before I used it so I stuck it in my stash.
Looked today and it was 1 Yellow and 3 Green slots! I thought I made a mistake and kept the wrong one but when I just looked it is now 2 Red, 1 Green, 1 Yellow!
So something is amiss there! Not noticed this on any other crafts but could be worth checking.
