When I reach the summit, expecting to meet Parthunax, he is nowhere to be found. Strangely, the first time I got there, I didn't know there was anything wrong because I didn't know what to expect; after bumming around for a while, trying to make something happen, I saved and exited. When I loaded that save today, lo and behold-there was a dragon-wall looking structure, though there hadn't been one last night-still no Parthunax, though. I reloaded an old save from before getting the clear-path shout and made the journey again; this time the Wall was partially there, but incomplete, though still no Parthunax.
I don't get it.
Any help would be greatly appreciated.
Thank you.
