rezzing old thread, but this generally happens when the event fires ( in my cases ) and the head of faith got converted.
this feels like the issue:
in the scripted effects, aerulan repeating scripted effects
create_aeluran_advisor_effect = {
create_character = {
template = aeluran_sister_advisor
dynasty = none
location = title:b_cykma.title_province
faith = global_var:high_matriarch.faith !!!!!!!!!!!
culture = root.culture
save_scope_as = aeluran_sister_advisor
}
}

thanks a bunch!
