I solved the puzzle and found Patrick's deed. I wanted to come back for it and the items in the chest at a later time. I was going to leave when I had troubles finding the portal stone.
So I got frustrated and screwed around with all the levers. I finally noticed the portal stone and went through it. Now I come back to get the deed along with all the other [nocando], and I can't open the door. I've put the levers into their correct positions and the door won't unlock anymore.
I'm thinking I might have to figure out how to use the hex editor to get inside, but if there is any other ideas I'd love to hear them.
I also ran into another glitch, but the item I lost was crappy: my weight limit was over to the point where I could no longer carry anymore. I removed an amulet so I could replace it with one which had a +1 trader's tongue bonus. As soon as I removed the amulet and went to swap with another, TOO HEAVY TO LIFT flashed up what must've been a hundred times and then the amulet vanished.
