I recently realized that human is the only BO-possible race that has, as a required trait, a space trait (leadership, +15% repair rate).
This is a problem because it means that human Bridge Officers have a trait that they can't use since Bridge Officers don't use space traits.
I would recommend that to fix this problem that Leadership be swapped with either Creative or Lucky; that way human player characters can select Leadership if they really want it but it won't interfere with Bridge Officer function.
