After returning the horn and being told to speak to Wulfgar to complete my training, he just waves his arms and fails to cast the shout on the floor. I have died a lot trying to kill them all in frustration and have added it to the wiki bugs list. Any one else have this problem or know of an official list of known bugs so I can see if its going to get fixed?

I also have the same bug with The Horn of Jurgen Windcaller quest. Arngeir (the one greybeard that can talk) is suppose to walk inside so you can learn the word of power. However, he just stands there saying the same thing over and over again. I was hoping the patch 1.2 would have fixed this but it has not. The worst part about is now I have The Throat of the World quest where I have to go talk to Arngeir but I cannot since he is stuck in a loop, thus I can't continue with the main story quest.

I also try attacking Arngeir to get him to chase me inside High Hrothgar, I got him inside but it did not fix the quest.
