Mirage In Haunted House Incompatiblities

Ok, first, this is just bad luck but its really sucky bad luck. I got the Mirror for the mirage IN THE BOSS ROOM. this means the mirage was no bigger than the boss room since the boss room is far away from the rest of the map.


The other, - I getting Eater Altars for the boss....but the boss is unavaiable.
