It is not a bug, whenever you do some sort of quest, it GENERALLY does not tell you where to go. And thus i'm more oftenly using that gamepressure guide to remember the locations. It's like, i'm playing world of warcraft (remember that game's Q log doesn't tell you everything aswell) but that's divinity, hell i like it. As for the place of HoE, it is in the minispoiler:
Below the place where the tree of Irminsul is. Check the map which is given for Orobas Fjords in gamepressure site. It's at the point: Eighteen.
Have fun.
