Doesn’t show up in logs but I think it does work, go to the sun reflection area thingy and rotate all the disks to face each other or rotate them twice, then go under the middle temple and choose the broken vase.
I’m sure there’s more to the quest but I can’t remember at the moment, you had to find pages and a journal before you activated the quest but it looks like you already have done that.
You need level 35. In the picture you are level 30
It doesn’t register as a quest. It did this for me too, I just completed the quest. It is technically a quest, but it doesn’t register for some reason. It’s just a visual glitch.
You’re underleveled. It’s 35+
Not a bug.
