Get Hek'd Achievement

Gameplay Achievements
1

Ok so I’ve done most of all the meta achievements for this but I am so stuck on the vilescale pearl. I’ve located the area where it drops from but this appears to be majorly broken for me cause the mobs aren’t dropping the pearl. Is anyone else having issues with this? I can’t imagine the drop being this bad, I mean it’s not a mount or a high dps item, its a white item.

Edit:
For what it’s worth I’ve done all the other meta achievements so this part for the pearl is the last one. So this shows I’ve done all the required pre-quests so it doesn’t make sense why one step would take HOURS and literally hundreds of Naga have been slain with no pearl. During this time I’ve managed to get about 3 of the Abyssal fragments to drop which leads to a mount and those are super rare. What is going on here? there’s something broken here and it’s pissing me off.

Note that the item is unique. If you’re not getting one to drop, it may because you have one hidden away in your bank.

Edit: I found it in my reagents section of my bank which I totally forgot about. Blizzard may need to work on giving us more notification of items hidden in the bank like maybe a option that’s grayed out so we don’t go waste hours trying to get an item. If it’s grayed out it would give us some sense to check bank and reagents tab ugh.
