Resolved Quest - Experience of the Ancients

Bug Name:

Quest - Experience of the Ancients​

Bug Description:

Can't make progress in quest​

How to reproduce/proof:

This is one of the quests you get inside of that excavation site beneath that hill near start zone.

I interacted with each murals (stones with text on them) BEFORE taking quest. Now the dialogue on the murals is gone and I can't finish the quest. I tried forfeiting quest and taking it again. I also tried closing the game and reentering. Nothing helped.

Edit: Made another character and this time relog helped me finish the quest. Until relog, the quest was "in progress" It seems a lot of early quests behave like that​

 

It's not only early quests.
Same issue occurs every time you face knowledge quest you already know.
It also happens when you get black spirit reward quest after each boss fight.

You don't have to make another character, just re-entering the world will do.
It started to happen mid June I remember but haven't got fixed since then.
