I just finished the raid last night. I had 3 keys because i did the complete raid all in one sitting, and went to bed. Got on today, and all three of my keys were not in my inventory. That is really messed up. To do the whole raid for 4 hours, and have my keys taken from me. I did not create a new character. I just went to bed, and got back on to learn they were no longer there. Good Job, Bungie....Not....
