So is there a cheat code that will create the specific rogue stone found in that house, or is there any other way of fixing this quest?
Edit: Nevermind I guess. It's been nearly 24 hours since I originally posted this question and I guess I'm getting impatient and want to play so I think I'm just going to start over. I really need to learn to remember to make more separate save files instead of just using quick save all the time. With my current game I'd have to go back a couple of chapters to the last time I actually did a proper save, so I might as well just start from the beginning again so I can fix other things I did wrong as well.
I'd just delete this post if there was a way to do that, but since there's not, I guess people can still answer the question if they want to, but I'm not going to keep my current game, so I won't have any way of testing the answers.
