I have now completed the Pit of Heresy flawlessly twice and although the stat tracker is recording the flawless runs the "Eternal Heretic" triumph is not unlocking. After my first flawless run did not unlock the triumph I decided to be extra careful on the second attempt, of which the match can be found here: [url]https://www.bungie.net/en/PGCR/9289378959?character=2305843009263669828[/url] To answer some likely questions: 1) I was the host, my fireteam gathered in orbit before we started the dungeon. 2) There were no noticeable connection problems, errors or warnings. 3) At no point did I return to orbit or leave the dungeon. 4) Other members of my fireteam did die. Some people suggest that this is a bug, and others claim that now the entire fireteam needs to go flawless, however there seems to be no solid evidence for either of these opinions. I also know that this used to be achievable with other members of the fireteam dying as that is how a few members of my clan achieved this in the past. Can anyone provide a solid answer to why this triumph isn't unlocking?
