The Chaos knight dwarf challenge game from week 3 of year 2015 has the 'You are forcefully drawn towards stairs leading downwards. Moving away from them after having discovered them will cause damage.' limitation.

My Chaos Knight was generated with the 'Your antennae explore the details of your environment (Ap: -4)' corruption.

The antennae activated and revealed the last lair. However since i had not opened the door to that room and actually SEEN the stairs, i was not receiving damage from the challenge limitation.

EDIT: added save file with bug occuring.
