Ive recently got a quest from Brumwulf Free-Winter in Windhelm to kill a bandit leader in Uttering hills camp but it's bugged if you already did the Thieves Guild quest to kill the Summerset Shadows so I can't finish it. I'm currently playing on the Xbox one so I was wondering if there is a mod to fix this quest and if so can I remove it after I finish the quest to get achievments? Also I don't have a save I'm willing to lose progress for.
