The back to the depths achievement in nazjatar does not get any progress gained after doing the scenario that spawns every 3 hours. I have killed it many many times working towards the Undersea Usurper achievement and have had 0 luck getting the achievement. Please help so I can get the crab mount.
I am having the same issue. I even tried disabling add-ons…didn’t work.
I have been monitoring this for a few weeks. It broke in one of the pre-patches (the same one that removed some achievement progress - a problem that they have since fixed)
I did get credit one since on the third attempt but not again in about 20 attempts and suspect that though Azshara announces the summons, the skull appears on the map, you can target and kill the summons…the scenario itself is not activating.
When it works scenario information should pop up on the screen in yellow letters, and a timer with a blue bar will count down prior to the summons. This has not happened in many many attempts.
To reiterate, I believe the achievement is tied not to a kill (which you can clearly do) but the completion of the scenario (which you currently can’t)
They will need either to fix the actual scenario activation, or possibly alter the achievement to give credit on kills instead of scenario completion. I’m no techie but that would be the first solutions I’d come up with…it’s a shame it’s attached to a meta cause it will create a barrier in more than one way.
