When I go into xEdit and look for conflicts, I see that SFSBGS050.esm is overriding a variety of other mods, in a fashion which conflicts with my load order.   For example, SFSBGS050.esm is at position 11 in my load order and LastNovaBackrooms.esm is at position 32 in my load order and yet SFBGS050.esm is mysteriously overriding LastNovaBackrooms.esm for CrimeFactionCrimsonFleet's faction relations.
