What do you mean by "nothing special" areas?

I can't see any problem in the code:

if (!ValidCoordinates(x, y) || !IsOpen(x, y))
{
x = pc.x;
y = pc.y;
}

The edges of wilderness areas which allow transitioning to the overworld map (described by 'l'ook as "Nothing special."). Since attempting to move into these squares prompts you to leave the map, items there are impossible to get back by normal means.

Fixed. And fixed another related special case.
