Subsystem-related crash

Alrighty, anyone have an idea what would cause an access violation crash when I enable the following subsystem on a ship:

--StartShipHardPointConfig(NewShipType,"Research Module","Weapon_Gun0","System","Innate","Damageable","BII_ResearchModule","","","","","","","","");

The joint name is in the ship’s HOD; the HOD and SUBS file are present in their appropriate folders, all the family names seem to line up, and the ship works fine with the line commented out (well aside from no research of course). This same SUB/HOD combo work fine copypasted to my other three factions. It’s just this BII faction that’s being stupid and crashing.
