at the orc ambush after leaving dreadfel, my anorithil placed a jumpgate down, got "killed", and the stairs out was generated on top of the jumpgate, I turned off jumpgate, and it erased the stairs with it! Was stuck in there for 900 turns while the rod of recall recharged
edit: the rod of recall fizzled argh. So is there a way to turn on debug mode or something to get out?
