Can't progress in the lvl 7 Ancient Cube quest

As reported in the title, I encountered a problem while carrying out the lvl 7 "Ancient Cube" quest in Poeta: Breavrunerk's magic box does not appear on the islet in the center of Cliona Lake. I've been searching for two days and I still haven't figured out if it's a bug or if the developers simply decided to change its place! Can someone help me? Thank you.

PS: it's my first post, I take this opportunity to thank GF and NCsoft for not letting the original Aion disappear. I'm only sorry that I didn't find the Italian language again, dubbing and translations were at excellent levels. I'm also trying the live server, it's changed a lot since the last time I logged in years ago (collecting skills no longer exist or am I wrong? Crazy!), I hope it's still fun and engaging

No, I'm sure that in the quest it indicates Cliona Lake. Confirmation on the wiki site https://aion.fandom.com/wiki/Ancient_Cube , and furthermore on the live server (where this quest has apparently been deleted) the box is still clearly visible!

I see, you're right and I'm wrong sorry for the useless report
