I've already fought Alduin and talked to the Greybeards to make a peace treaty with the Imperials and Stormcloaks. During this question I didn't finish the "Join the Stormclocks" quest so Ulfric refused to talk to me unless I killed the Ice Wraith. After finishing that quest, talking to Ulfric gives me an automatic response to talk to Galmar, when I talk to Galmar, he responds saying how he dislikes the opinion of meeting at High Hrothgar, even though I was unable to even initiate the conversation discussing the peace treaty.
Even though this game is great I've run into 4 glitches that have forced me to restart from a very early checkpoint, I'd prefer not to redo 5-6 hours of gameplay just to prevent this glitch. Has anyone else encountered this problem and if so, how did you overcome this glitch?
