Currently completing the Let Me Solo Him: The Underpin does not award you the Delver’s Gob-Trotter Schematic: Gold. If you are in the same boat, or it happens to you when you complete the achievement, do a bug report so blizzard are aware.

They at least acknowledged the bug. I reckon it will be hotfixed soon as a lot more people are killing him now.
Killed him multiple time, they said it’s fix now but still didn’t get anything…
I did it tier ? tier ?? and also as a group to be sure… But nothing. (latest kill in tier ? and ?? was again this morning after this message from the dev).
Our developers have fixed the issue that was causing this problem. Please try again.
For anyone with the achievement already unlocked, the schematic should drop on any difficulty/group size.
Edit: Also they should fix the adds who don’t go down, I noticed that they go down at first if you make them spawn turning around the arena, but once you’ve done a full turn, it seems that the adds dead body don’t totally “disappear” even if you can’t see it anymore and cause the next adds who try to go down, just staying above.
So it look like an add can spawn only once per spot and per fight, it mean if someone don’t have enough DPS to kill the boss before a full turn it will end up buggy.
Yeah they didnt fix it at all.
I killed it again after they claimed it will grant the schematic, but that was not the case
I killed twice today, got nothing on both kill.
Extremly frustrating
Literally just killed him not 15 mins ago and spent that time trying to figure out where my reward is, i’m amazed it still isn’t fixed yet. Guess I’ll put in a bug report as well
It’s finally fix guys !! Just kill it in any tier if you don’t receive it and it will drop as long as you’ve the achievement !
