For those budding modders that are trying to fix some of these 3rd party races or units; the game will crash when the unit is built or dies. The fix is to go thru the unit's/unit's_dead 3do and check for 'none' in the faces. Replace the 'none' with the nothingatall texture or some random texture. Save, repack,run and check the unit in game. However, there are units when the unit's fbi calls for a corpse and there is none in the object folder or the script calls for one and there is none in the fbi but that is a different problem altogether...
