Angarvunde
Ancient's Ascent (wall is outside, in environment, not in dungeon)
Ysgramor's Tomb (quest locked)
I've been to angarvunde but I THOUGHT not the over two. Definitely not the tomb cause I haven't started the quest. Then there's ancient's ascent, already on my map, AND listed as cleared. Odd I thought (when I had to go there for a small bounty quest) since it was way up in some mountains and there was no other areas "discovered" near it. Upon going towards that general area, I find out that the only way to get there was through bonechill passage (a cave) that I've NEVER been to. So there's this dragon wall...up in a place that I've apparently cleared, and the only way to get there was through a cave I've never been in/discovered. Also, I turned off collision to go up there quickly, the wall was blank (learnt it already apparently) and the chest there was empty! Either the game somehow thinks I went there already, and gave me the shout/chest, or in some dreamwalking drunken stupor, I turned off collision, cheated and flew all the way up there, and don't remember it. And I would never cheat like that so I'm very perplexed.
Any ideas on what happened?
