[Anziel]

So i used the forge and killed the boss but the quest marker is still there same thing with teahouse

[RACHMANOVSKI]

Does the quest in your journal completed?

There is a bug on quest marker stuff, but haven't heard about adamantine forge so far.

[SuperRenier]

Same, I just killed the boss, got the loot, but the quest marker doesn't go away, with nothing in the Journal

[Vergil]

Same. But I just had to save the game then reload it from that save and that fixed it.
