yes, I read the scroll, I have the sigil and the shield as well, the door seems to have appeared but I can't get close enough to it for activation. I have traipsed all over the little valley, and all up against the door, but there seems to be something invisible blocking the path straight up to it.
It seems to be a bug in the new patch. I've contacted support who are looking into it.
I worked around it by reinstalling without the recent patch, which removed the barrier, got close enough to access the door, saved, installed the new patch and resumed the game. Which is admittedly a bit of a hassle, but it's better than not being able to proceed!
I can't guarantee that there's no unintended side-effects using that method, but I didn't notice anything obvious.
