I just lost my Thorn last night with the app. I work in IT. I know darn well Bungie has data indicating I actually had the thorn and that I didn't "accidentally" dismantle it. Much like Otaku's IB, we lost these due to a bad line of code from Bungie. I love the game, but c'mon. I was switching characters and almost had it maxed so I was going to toss it on my hunter to try to max it. Instead I lost it. I stink at Crucible so that took a while for me to get. :(
