Since it looks like that save's a no-go, I decided I'd speedrun the main quests through again using a god mode trainer, and finished five Jarls in one day. Now I have a whole new problem. I finished the monastery and got the Thjorad Hammer before talking to Sven, and when I did I told him straight away that I'd found it. He took it, but now he's stuck in a dialog loop and I can't finish his other quest!

I tried removing the Thjorgard and monastery minisaves, and the Thjorad Hammer is back where it was, but now I can't pick it up. The monks won't move when I redo the bell quest, so I have to kill them. Do the unofficial patches fix this?

By the way, thank you very much for all your help so far.
