I'm stuck. I'm trying to send blue light down from the top floor to the bottom. I'm in the NW corner of the top floor, with blue light coming into this pillar. The tip calls for a mirror to be inserted on the east and west sides of this pillar to shoot the light downward, but there is no west side on this pillar. I can't insert a second mirror, I get a message saying there already is one here. I must be doing something wrong, but can't figure out what. Any help out there for door 3 on mournings end part 2?
