Description for #6 means "southern boulder" (of many) - but there's only one boulder there. Around #2 and #7 the map has too mape contour detail for CF to convert accurately, try to remove some curve points in OCAD before conversion.
HELVETE! Run ON the control without seeing it! some missing missing contours, I think? Did you have the Idre ocad? But keep on doing OCADs and you will improve nilmag!
