DISRUPTION Cache Skin
So I just got the DISRUPTION Cache and was SUPER excited about this for the Icon and everything. Another reason was because the only Project skin that I didn't own from the last set was is Project: Yi. I figured it would be pretty awesome since this is a pretty pricey skin and since I owned all the old ones this would be the one that I got. This morning when I bought and opened the DISRUPTION cache it gave me a Project: Yasuo skin which is the first Project Skin that I ever owned from way-back-when.
Is this how it is supposed to work? Even though I already own the skin there is still a likelihood that I will pull an already owned skin from this cache that is limited to previous released Project skins in which I own all but one?
Thanks!
