+PU_FAILURE_INVALID_GOAL          Goal is not on the navigation-mesh and cannot be reached.
+PU_FAILURE_INVALID_START         Character cannot navigate from the current location - e.g., the character is off the navmesh or too high above it.

+PU_FAILURE_TARGET_GONE           Target (for llPursue or llEvade) can no longer be tracked - e.g., it left the region or is an avatar that is now more than about 30m outside the region.
+PU_FAILURE_UNREACHABLE           Goal is no longer reachable for some reason - e.g., an obstacle blocks the path.
