The only cheat (sort of) is when you get to a room with a chest, or a named spawn, and you have to open the door, you hit backspace until the door is targeted again, and "use" the door, it closes the door again, and open it to spawn the named npc (if he didnt spawn before) or respawn the chest that was in the room. I have tried this, and it works, but its not that useful, except in some dungeons.
Anyone got any new stuff?
