I used a translator. please understand. This issue also occurred with the release update for 'The Witch Queen'. Since the 'The Witch Queen' release update, there has been a serious bug where Season 12 Harbinger Mission Triumph 'Leave None' is marked as incomplete. This is not only me, but other players are also experiencing the same issue. Other players reddit posts: https://reddit.com/r/DestinyTheGame/comments/t0nrf2/leave_none_triumph_bugged/ https://reddit.com/r/DestinyTheGame/comments/sz1y6o/harbinger_legacy_triumph_leave_none_3510/ And this is my data record on http://light.gg that I have completed Triumph: https://imgur.com/a/tAIIN3Q I've mentioned this issue every season on Twitter and the Bungie forums, but haven't gotten a response yet(I understand that not all posts can be answered.), and ended up running into the same issue on a bigger scale. I hope you will be investigated previous issue together, as you investigate the current issue.
