SMALL SPOILERZ AHEAD:
Is anyone else's "Discerning the Transmundane" quest glitched? In mine, I went to Septimus's outpost and delivered the blood to him, the door opened and he went inside. There was a book sitting on a stand. I tried to take it, but no matter how many times I press "E," it never lets me take the book.
Meanwhile, Septimus is just walking around by the book stand with the quest marker still over his head and when I try to talk to him, it says he is busy.
So I was like fuck this, I go and do a ton of other shit and come back and the chamber is sealed shut. Septimus is still inside the chamber with the book and the quest marker is in there also.
WTF?
