Okay so if this has already been posted I'm sorry but I did a search and nothing came up when I searched for it. Bungie says there is a sixth chest and it's not as complicated as everyone is making it out to be. Couldn't find anything on it being found yet (I'm guessin cause everyone has moved on). I found this area which is right as you go into the vault off to the right and it looks like it's just an area that you fall into and die. It's not though you can go all the way down to the bottom on the ledges. I was doing this on the Queen's mission so a chest wouldn't spawn anyway I don't think. I'm just wondering if this has been tried. I know it's probably a stupid theory View from further down where death should have triggered: https://41.media.tumblr.com/20757dd1d37d499db8a41fc343e6b803/tumblr_novomhCqtP1twiavwo2_540.jpg
