The Golden Camel UberBadge is a mystery. Nobody knows where it came from or how it got there.
No one expects the Spanish penguin!
Even in base game, if something makes you place a tile without "discovering" it, you wouldn't draw its card.
Because errata for the first edition changed such that icons in the new room do affect you (to prevent the possibility of no haunt), I play that icons for newly revealed rooms always affect you.
That's how oh first turn I got sucked through the walls, stumbled onto a wall switch, fell through a floor and landed inside the mystic elevator which ended adjacent to the collapsed room I feel through. Four rooms explored in the first turn of the game.
