Quest Issue: Coldain Ring 7

[Odemous]

Hello, I have been trying to help a buddy with his 7th coldain ring quest. We kill warden bruke then turn in to blackwell, who is imprisoned nearby. Every time he turns in ring 6 and the key, blackwell just respawns standing, in the imprisoned ones spot, but does not say a thing or move. We have attempted several times now to the same effect.
