That's sad to hear, I was bummed when I finished the raid and all my keys were gone. Lucky it also happened to another guy in my fireteam as well. Is anything being done to compensate those who lost the keys? I guess it's good we all know the root of the problem I'm just still really bummed about it. It's the little things Bungie... disappearing Raid keys, duplicate exotics (like 8-10 of them), nothing dropping out of cayde -6 chests. Everyone loves the game but things need to be ironed out cause I know a lot of people that are also upset.
