about Retrieve the Helm of Winterhold bug i avoided doing the quest or discover the location Driftshade Refuge" before doing
blood honor quest but now i went to Winterhold and the jarl skipped the quest and the dialog showed (do u need anything else )
so he told me to help Winterhold citizens .

from what i remember i did Retrieve the Helm of Winterhold before blood honor but what made me wounder is that when i accepted
Purity of Revenge i was sure i was in Driftshade Refuge before but i kinda messed with the saves the day earlier .
so Driftshade Refuge wasnt explored yet .. anyone can tell me what happened ?

well?? no one knows ?

Glitched for me too, most likely from clearing the place first.
