This is the second week I've erroneously lost my raid keys. Tonight my team finished the raid, and all went to get the chests together. After re-entering the raid (no, I did not switch characters), I found all my keys had disappeared. This is NOT just happening with new characters, or characters below level 20. I must say, it's very frustrating to grind the raid out, only to not get loot from it, because of a bug on bungie's part. I literally haven't gotten to open the raid chests at all, because this has happened to me every. single. week. since the raid dropped. Please address this bug ASAP, and make sure and give us our keys back!
