I have finished this 3 times.
First finished while I was downed. (Monday: 8-22-16)
Second finished without me ever going down. (Monday: 8-22-16)
Third finished when I was down. (Today: 8-24-16)
I used a Revenant for this and as of today a bunch of revenants I was with got it except me.
I can no longer guess what the problem is on my end but I submitted the ticket on Monday and have yet to receive a reply. I haven’t even received a reply from a ticket I submitted on Friday 8-19-16
