I don’t know why but for some reason I can’t interact with the magic circles at all.
Not sure if it helps but I did the boss battle with party instead of solo like I usually did.
EDIT: Just realized this was in the wrong section, my bad, mods can move or delete this thread.
Are you referring to that part where you have to find some tools? That you take at around level 50?
In that part, most of them will just say that they are of no use to you, until you find the right one.
But if you say there is no reaction, then it could be just lag. I just completed that section recently.
No, I’m referring the the quest that you get from Saule right after you kill Harpeia (the bird boss).
I can’t interact with the quest object at all, I’ve tried abandoning the quest, re-logging, and then taking the quest again but I still can’t interact with the object… I’ve even tried mashing space bar near it but still nothing.
There’s supposed to be two quests that you must do, one being across where you are at. Try looking at the maps for quest icon.
Just a quick update, for some reason the issue has fixed itself I have no idea how that happened 
They require your char to be 45lvl, but it only tells you that if your party member starts it.
