This did not happen to me but my buddy. We always play together and try to do all activitys with just the 2 of us. I bought my gjallerhorn from xur in week 2 and it always came in handy on those tough bosses in pve. We were playing for so long hoping every nightfall that gjally would drop for him. So 2 weeks ago xur sells gjally. Soon as I get off from work im texting him saying: XUR IS SELLING GJALLY!!!!!!! Both of us really excited for us to finally have 2 gjallys. I get home and hes online already bought the thing and he is stoked right! So he buys the exotic engram too to rank up is cryptarch hoping for a legendary. Ranks the dude opens the package its a heavy engram and it decrypts into gjally. Man o man I almost pissed myself
