1) The quest "In the prison of souls" seems to be broken, or I do a mistake somewhere. I got the quest from the ghost on the path to the Mana Catalyst. I have explored and cleared out both parts of this dungeon a while ago. The quest asks me to find a stone in order to unlock the souls from their prisons. The souls seem to be in jars in the upper part. I was able to find something that looks like a glowing stone in the lower part, where The Steerer (boss) was, but it cannot be picked up. I don't know what to do, and I might have gotten something wrong on the way.
2) The Shadow God quest in Zerobilon has the marker pointing towards the room with the "games" teleporters, but there seems to be quite a problem with this. After running around in circles, I found the third teleporter in a stone ball identical to the other two, but it's fixed to the ceiling. Without the help of console commands, it's impossible to reach it. Is it another way into this dungeon?
