I played vault of glass to kill atheon to get it. I finished the vault of glass on hard mode and I didn't get the weapon. I did not have a weapon slot open for it it was full. Does it not give it to you if you don't have a open weapon slot? it was on hard mode. I spent 2 hours doing it and I'm really mad because I wasted my time to get the weapon I didn't get it. Recommendations? What could I do? I don't want to go thru that again. You can see I competed it on my profile. Thanks.
