Seriously, is it turned on?
Now I know thay better chance of crafting is working as have got an epic from all common. But I've bought fuel tanks done close to 40 hard scavanges and some challenges have had 1 common fragment, about 3 common components, 2 green and 1 leg frag. Bearing in mind in two weeks ago I got 7 in 5 days. I thought this would be like the phone and gold rush event I.e get a decent amount of components every so often 3 from the first three crates etc... grrrrr rant over.
