Incorrect color on exit list

[Scion Altera]

If:

• You are one room in from the border of a zone
• It shares a border with another zone
• The room between you and the next zone is empty

The direction shows up gray as if you could walk into that room and create a new zone.

When you try to go in that direction, you (correctly) get the "Alas, you cannot go that way." message. The exit should not be shown on the exits list because it is not in fact a valid direction that you can go.
