It appears if you run a party of of say,
A, B, B, B, B, B
with A and B representing two different races
with Outcast not longer, the cockatrice trait, and We are Pack the tribalist perk,
then what happens is:
B, B, B, B, B, B
which is consistent with the tribalist perk applying first, then Outcast no longer not doing anything.
I was expecting:
A, B, B, B, B, B -> A, B, B, A, A, A (via Outcast no longer)
then, -> A, A, A, A, A, A (via the We are Pack perk)
