UPDATE: I ran it again and I was able to complete it all in one session without getting kicked, and I got the triumph this time (not a flawless run, but I'll get there). The initial problem of not registering the first time was most likely due to Bungie's issues today as we discussed below. Thanks. =========================================== This is an odd one. I just completed GoA dungeon solo. When I killed the final boss, I got the loot and saw the triumph banner showing up on screen. With much surprise, when I went to redeem my triumph, I realized that it did not count. It says that I still have to complete this dungeon solo. Note that no other player joined my fireteam and the activity at any time during the run. As well, I have not joined anyone else who was running this dungeon. I must say I'm a bit disappointed considering it took quite some effort to complete it without dying many times.
