Haunt #22 room choice
The good news is that it's impossible for a floor to lack an available door. The bad news is that it's quite possible for the Heroes to be standing in all of the rooms of a floor that have an available door.

This is a hole in the rules, and there is no rules-strict way to solve this. I can suggest a few alternatives, with my favorites first:


Allow the Traitor to select any room on the outside of a floor (i.e., pretend that all of the rooms have doors in every direction for the purposes of selecting this room).
Allow the traitor to select a room with a "false door", that doesn't go through to another room because the other room doesn't have a door. (This will be a room in the middle of the floor somewhere.)
Fall back to the "floor has been sealed" rules, and permit the current player to rearrange the floor to produce a room with an available door that does not contain a Hero. Note that who gets to rearrange the floor is going to drastically affect who wins, and it's currently the Traitor's turn.
Allow the Traitor to select any room on the floor.
