PSA: Ring 7 Quest is broken currently

[Moodie]

Just a heads up, it appears the ring 7 quest is not working as of today, when the ring and key are turned in to the dwarf he disappears. Ring is returned to the person turning in but key is lost.

Greetings!
It appears there was an instance of a double-spawned, Corbin, which would result in the quest not progressing as intended. We are still investigating the matter; however, the second Corbin has been removed and the quest should be operational. If the problem persists, please do not hesitate to let us know.
