please update

Any chance of doing Federation Ships and Portraits ?

@Arcane Flame - Really apprieciate your fix! I reuploaded the mod (due to my inability to update it) and now it should work perfectly. Thank you! :D

From what I can tell the issue is with the species classes file where both the Romulan and Klingon portraits are trying to redefine the Hum/Humanoid designation to add one or the other. A fix seems to redo the file like so:
KLI = {
archetype = BIOLOGICAL

possible = { authority = { NOT = { value = auth_machine_intelligence text = SPECIES_CLASS_MUST_NOT_USE_MACHINE_INTELLIGENCE } } }

portraits = {
"klingon"
}

graphical_culture = klingon_01
move_pop_sound_effect = "moving_pop_confirmation"
}

Same for the Romulan mod with their respective changes. At least that seems to have gotten it working for me.
