i dont know about anyone else but that sounds like a order of operations error to me
i haven't actually seen any of the code for this workbook nor could i actually edit this but i think its a matter of the Wyrdling being treated as Second at all times (which i personally think it should aside Considering the way you become one) and so only giving a +1 to Psy Rating
the only thing i can think that would cause this is how your character is a Wyrdling. Career Path option or a consequence?
