I am on the quest 'Waking Nightmare' and I am supposed to follow Erandur into the Nightcall Temple. I open the door to follow him in the Temple and he is nowhere to be found.
Without him I can go no further because he is to cast a spell so I can follow him through a figure on the stone wall. But without him I can go no further. Is this a bug in the game?

I am playing on Xbox 360

it's a bug. see if you can find a solution here: http://www.uesp.net/wiki/Skyrim:Waking_Nightmare#Bugs (depends on your platform)

sry, just saw the xbox part. looks like your only solution is a prior save.

Looks like it won't work with Xbox...darn.

Yea theu really need to release a patch that addresses this bug. Just a simple location reset on Erandur woulld fix it. Not everyone plays on pc and can phase through the wall using the console command.

I simply dont understand how such a huge and obvious bug wasn't squashed before the gmes release...
