Per request from the help team that cannot fix this issue, I am posting the issue here in case the devs lost the request already sent them by the help team.
I have been dealing with this issue since November with no fixes from devs yet. In November I achieved the Deadly Engineer achievement but the META for All Death achievements did not update with it. I opened a ticket at that time and was given this advice:
Response By Email (Removed by Snowthine) (11/18/2015 09:05 AM) ...Most in-game UI issues (including NPC, quest problems and missing crowns/entitlements) can be resolved by logging out for five minutes then back in which will load you into a new game instance.
I responded:

... It has been 2 days and the issue has not resolved itself. Additionally we have gone through the instance and done the achievement again and it is still not working. I have done the log on and off and on and off with no resolution. Re-completed the achievement with no resolution.

Many thanks for the report, though this is the end of what you and we can do. This information will be sent to the developers for review and correction. We are unable to disclose how we will correct this, we would have to suggest checking the forums for any updates regarding this issue.
Since then I have completed the last remaining Meta Achievement for the All Death challenges and have NOT been awarded the Meta along with the team I completed the challenges with. Because of that I re-opened the ticket to see how this will be fixed. Even though I was told that the Devs already have this info I was told to post here - so I am doing that now.
There has been no update, and there has been no resolution. Furthermore, I have checked VARIOUS forums and NOTHING I have seen in the last 3 months has stated anything about this, including patch notes. I will attach a screenshot of both items, my deadly engineer completed with date/timestamp and the pic from last year the day after we got the achievement, when I first opened the ticket.
What I don't understand is, we have RE-COMPLETED the achievement MANY times in 3 months, is there no way to just "delete" my progress on the ONE achievement so we can redo the achievement and re-trigger it for completion if updating it as completed in the meta this is too hard/time-consuming for the dev team?
