I'm really angry. It's the third time I'm finishing Skyrim, just to get the "Oblivion Walker"s trophy, because at the first time I missed some artifacts, and, at the second time, I missed Volendrung, by being hostile to the orc tribe. In these times that I finished the game I didn't knew that the trophy wouldn't be unlocked if I miss some of the artifacts. Now, at the third time, I was doing alright, and I've already had 7 daedric artifacts, but the quest "Waking Nightmare" bugged. Erandur dissapeared just when I went in to the Nightcaller Temple, and the wall was still there, blocking the way. I was not aware of this bug, I thought that if I left the temple and come back, the bug would be solved. But it not happened, and all the previous save was overwritten, I can't go back now. The only trophy that I didn't unlocked yet is "Oblivion Walker", and I just don't know what to do, because everytime I try to get this trophy, something crappy happens. Is there anything I can do, or I'll have to start a new game, again? =\
