Note to Windower users: a bug causes this quest to crash in Windower.
This quest is bugged in the same way that some other quests are. After you are given the earmuffs, and Traiffeaux says he'll go to an ice wall with you, the screen goes to black and stays that way. The chat log and the rest of the UI are still there, however. There were a few other quests that did this, and apparently using Windower was the cause. Normally you would just talk to the NPC/whatever again after you reloaded the game, but in this case, doing that will trigger the exact same cutscene again. The earmuffs and "Fragmenting" DO appear in your list of KIs after you reload though, so you may just have to avoid talking to Traiffeaux ever again. :P

I finished the CS by relogging into vanilla POL. The screen did not go black again. --vm0d (talk) 05:22, January 6, 2014 (UTC)
Same as others have stated. Windower bug. Relog with vanilla POL and you will be able to complete the quest. --Rehmii (talk) 17:16, March 7, 2015 (UTC)
