Figured the trigger. When turn on the valves of the chimneys, if ypu turn it off, and then on again, the game gets confused and do not register the change. When timer ends, everything disappear from hud, and you cannot even cancel the challenge. If you die twice then you respawn into your room, with the challenge's weapons.
