Using Event to give ruler a custom ruler trait

[Lord Sunderland]

So we have a Dalek Prescripted Nation. We've set the country flag to 60sDalek.

We create a new event file: Dalek_events.txt

________________________________________________________
##################
##DALEK EMPIRE
##################

event = {
id = 60DALEK.1

hide_window = yes
is_triggered_only = yes

immediate = {
every_country = {
limit = {
has_country_flag = 60s_Dalek
has_country_flag = add_60sDalek
}
country_event = { id = 60DALEK.2 }
}
}
}

#country_event = {
id = 60DALEK.2

hide_window = yes
is_triggered_only = yes

immediate = {

#Kill Our Ruler
every_owned_leader = {
kill_leader = { type = scientist show_notification = no }
kill_leader = { type = governor show_notification = no }
}
#Create Immortal heir
create_leader = {
type = ruler
species = owner_main_species
name = random
skill = 0
traits = { trait = trait_ruler_immortal}
}
#Make the Heir ruler
assign_leader = last_created_leader


remove_country_flag = add_60sDalek
}
}

Nothing. Zip. Nada.

If I apply the KSP Mod that I am attempting to emulate I can kill my ruler without issue but I cannot create a ruler or even an heir and three Kerbal named daleks appear.

Any Ideas?
