So I'm playing on the xbox360, and I got the quest by reading a writ of sealing from Jyrik. It then directed me to read the Lost Legends book which pointed me towards Folgunthur. I found Daynus Valen's journal outside, and then I found his notes on his body inside. However, my quest doesn't update upon reading his notes. Is there anything I can do to fix this, or am I forced to never complete the quest now?
