Quest in the Ghostlands given by Geranis Whitemorn on the island in Lake Elrendar. Still shows as available directly after completion.

Unfortunately I hid it manually after submitting this, how do I unhide to check that?

Go to Questie Journey ( /questie journey ) > Advanced Search and Search for the quest. Then uncheck Hidden.

Does it say Completed?

Ah, it does. Okay, good to know that I should simply reload in this scenario. Thank you for the help.

Does it disapperad if you /reload?
