Last night I was doing a run-through of Forelhost to get the Rahgot mask and the Storm Call Word of Power, when I came across a bug that stopped me dead in my tracks: The Nordic Puzzle Door at the end of the dungeon would not allow me to interact with it. The keyhole could be activated, but the rings with the symbols could not be rotated.

Anyone else run into this?

Ugh, yes. Some people have a lot of problems with these doors. If the rings aren't turning, run all the way out of the dungeon (which svcks I know, that place is huge) and then go back. This will allow the game to reload the dungeon and hopefully take care of the problem. Try it a few times. You can also try to go back to a previous save and try again.

If you had the situation I had, the rings turn but the snake symbol on the key is different than the one on the door (one faces up, the other down). I've tried everything to get through that door, no luck so far.

Good news though, you can still get the Storm Call Shout without going through the dungeon. If you jump up the big half-wheel like structure in front of the cave and use the Whirlwind Sprint Shout to get to the other side of it, you can jump up to the level and just walk over and get the shout. If my memory serves me correctly, you can't use the door up there to get back into the dungeon though.

Anyway, hope this helps. Good luck!

Okay, I'll give it a shot. Thanks!

Edit: Just tried your advice: The symbols rotate now, but like you said, the snake symbol is now upside-down and the door refuses to open.

I tried many times to get through that door and I ended up just moving on to another quest. You can still get the shout at least... I hate those stupid doors. I wish they would fix them. If you find any way to get through that door let me know!

I had that same problem, the rings would not rotate, I left through the nearest door and reentered, after I did that, I could move the rings, but still nothing happened when I used the claw.
I tried one thing and I could open the door, everytime I left I had the right symbols placed in the right position, but noting would happen.

I tried setting the symbols too three other symbols and then leave through the nearest door and then reenter the room, I tried the right combination on the rings and used the claw, the door would now open.
Don't know if this would help or if you have done it already, if you have not I recommend trying it, it worked for me.

Sorry for the long explanation, and sorry for the poor grammar.
