No Shellfish Endeavor

For those of you that have completed the 3 steps but no achievement until blizzard fixes this it would be best to open a ticket.
I had the same problem so I finally made a ticket about this and a GM granted me the achievement after seeing that all quests had been completed

No Shellfish Endeavor
Should reward [item=143660]

Requires:
Oh, The Clawdacity! Starts at King Mrgl-Mrgl, short questline. Clawdacity may be a prereq for opening the next two WQs.

Claw For Alarm! is a WQ in Suramar, on the east side near where the pylon WQ is at. 82,54.4 Is the egg you must locate. Turns you into a murloc, kill Naga in the area for assault on the Sashj'tar ruins, kill Sashj'tar Culinarian.

Now Thats's Just Clawful! is a WQ in Stormheim, egg is at 55.4,26.1. Kill 10 Rockclaw Clamcrushers, kill Clawspishus at 61.4,20.4.

As of writing this all objectives of the achievement are completed but I have not been awarded the achievement itself. I sent an alt over to do Clawdactiy, since my main had finished it prior to the patch, but after I finished it I noticed that the two WQs were not available.

Hello all,

Just dropping in to let you guys know that the game client can be inaccurate in tracking this particular achievement. This is something our developers are currently working to resolve.

If you think you should have received this achievement based on what you see in game, we recommend checking the armory to see which quests you still need to complete.

Sorry for the confusion!
