Missing Feline Figurine

Hi all!

Recently, I decided to go back to Nazjatar, as I really want the Undersea Usurper mount. I decided to go to complete the Feline Figurines Found achieve first, as it seemed like the easiest to knock out.
I hopped on my Pally, grabbed the co-ordinates from WoWHead, and collected 9/10 figurines. The last figurine, located in a cave at Azsh’ari Terrace (TomTom co-ords 55, 27) is seemingly missing.
I have submitted a ticket and bug report, but a GM replied saying that it seemed like it wasn’t a common issue as I was the only one with a ticket open. I vaguely remember picking up a crystal figurine way back when Nazjatar was current, as I mained Pally at that time and none of my alts have any progress towards the achieve.
As for troubleshooting, I followed all the regular steps like disabling addons, reloading my UI, loading out of Nazjatar and back in etc. but remain unable to see the figure to collect it on my Pally. It’s there on my Druid, which makes it seem more likely that I have picked it up and the achieve messed up somewhere in between patches and wiped my progress.
Has anyone else had an issue with this? I know it’s very specific. I would just start it all over again on an alt but the Undersea Usurper achievement takes so freaking long to work up I can’t deal with the idea of starting again.
Any advice would be fantastic.
Thanks!

2 years later and after spending 10 min swimming around the cave, zooming in and tilting my camera at weird angles, i watched a video to see that the cat is supposed to be under the starfish on the ground, only to realise it is not… I then read every single wowhead comment and someone said the area seems to phase and hence, i did every side quest i could find on the map (I had already completed the main storyline lol) but to no avail, still cannot see the cat :frowning:
