When Gale dies you get the quest in case of death. Love the permise etc. It just functionally is broken. I opened the pouch with purple seam, played flute correct, the mephit however you can't talk to. The game doesn't recognize that it's really there. It's just flying in place not highlightable or interactable.
Side note: it's really annoying how much damage the necrotic damage does because my companions keep walking through it like morons and ending up nearly dying.
thankfully I should be able to resurrect him with a revivify but I hate that I miss a whole story arc and the possibility of saving the scroll because of this bug.
I'm playing on Stadia, game version 4.1.1.1.1344113
