there is a bug in the caves where a spot has two options to go south replacing the option to go east the other direction making that place impassable in that direction.
the spot is the one to the immediate north west of the middle spot with only one entrance.
and now the spot two steps south of that (immediate south east of the middle point with only one connection) east option does not work
also the compass image on the east option in a lot of spots is pointed the wrong way
