I used market raid twice on this market https://i.imgur.com/3lwLaTj.png
and got lots of zinc, nickel and barbed wires, but only 1 lead bar two times!!!
I suppose I got only 1 lead bar, because I didn't have learnt recipe for Lead Bars crafting? But that should not matter! Hey, I am raiding market, why would I get only 1 lead bar?! That's unfair and painful experience. :-(
