Same thing happened to me. It was a daily mission today and I played the mission on level 28 which is not easy for me because I needed two ascendent shards to level up. Once I got to this glitch in the level I went back to orbit and replayed the mission all over on level 28 only to get the same results!! It is extremely frustrating when all I needed was 2 shards to level up and I can't even get it because it is unbeatable. Bungie seriously needs to fix this. and my only question is if they were aware of this bug on November 10th according to a user post then why would they post it as the daily mission if it is not fixed. I was really looking forward to getting that today ...I feel like I deserve 4 shards after going through all of that!! playing on level 28 is not that easy for a level 26,
