Smooth Cave Instance: Leave the Minimap

[ZorkNemesis]

This is specific to the instanced map "SmoothCaves_60_Layout_07" but can potentially exist on other maps.  The minimap for this mission is smaller than the instance itself and it is possible to go far enough into a specific corner that the minimap will display "Map Unavailable" until you return to the "boundaries."  It would seem that the point of exit is right at Z: -1408, and can occur in the very northeast corner of the map in question.
