Birna and Ranmir just stand outside Birnas shop and do nothing.

Birna gave me a claw but i didnt catch where it goes. Its not a quest item as I can drop it. Birnas shop is always closed so I can't buy anything.

I left Winterhold for ages but when i come back they are in the same place.
ANyway to get them to go back to what they should be doing?

Cheers

The claw is for here:

It is not far from Winterhold (To the east of it, I think).

Keep in mind that there is a very odd bug (Not sure if it was fixed yet) that makes the screen all hallucinate if you have a follower with you. Leave your follower outside to fix this.
