Trying to start making skyrim mods and was getting pretty far till I had an error after putting daedric cuirass through nifskope changing value from 12 to 11 and value 2 from 83 to 34. Tried to import it like I've done several times with body parts, iron armor pieces, and ebony armor pieces but this error happened -> ValueError: Unknown block type 'BSInvMarker'. Program versions: blender nif script 2.5.8 blender 2.49b nifskope 1.1.3 pyffi 2.1.11 python 2.6.6
