I noticed this with more items, be it weapons or armor or whatever... It's always 1 item which just never seems to drop.. The same with the black armory.. I've salvaged a lot of weapons by now and not even 1 where the Refurbished shader is on has dropped it.. And it's just a rare shader, not even legendary.. Maybe I'm just sacrificing the wrong things to RNGesus... Better do the sacrifice backwards since it seems that's how this game is set up..
I’ve heard a lot about that refurbished Shader, I’ve dropped like 20 but it seems to give a lot of people hell. Idk, could just be unfortunate RNG
