Hello!
I currently making mod which provides compatibility between different trait mods and 30+ portrait mods.
Noticed that many of your specific traits fror some species classes missing species_classes so they actually can be applied to any biological species.Example:

trait_love_of_cubs = {
cost = 2
potential_crossbreeding_chance = 0.50

modification = no

allowed_archetypes = { BIOLOGICAL }

modifier = {
pop_happiness = 0.10
country_trust_growth = 0.20
planet_pops_consumer_goods_upkeep_mult = 0.05
}

}

Obviously this only for mammals, but without species_class = { MAM} it will be applied for all Biological species.

Not sure about activity there so in my mod i temporarily fix this issue despite it doesn't supposed to do that.
