Why is the Underground Lake on the upper floor?
See, it’s a special kind of levitating lake, and… All right, it’s a misprint. Here’s how to handle the Underground Lake. When you find the lake on the upper floor, the floor collapses, plunging you down through the ground floor and into the lake in the basement. Put the Underground Lake tile next to any door in the basement (put it next to the Basement Landing if no other tiles have been played in the basement yet). The spot where you intended to play this tile on the upper floor is still open and a different tile can be played there the next time it’s explored. You’re now in the basement on the lake tile.
