Trait: IAmPope ?

I looked around in the export_descr_character_traits.txt and noticed:

Code:

Trait IAmPope Characters family Hidden Level Character_Is_Pope Description Character_Is_Pope_desc EffectsDescription Character_Is_Pope_effects_desc Threshold 1 Effect Level 1

and

Code:

Trigger factionleader_pope WhenToTest BecomesFactionLeader Condition FactionType papal_states Affects IAmPope 1 Chance 100

I used give_trait 'character' IAmPope and nothing happened except the priest became a bishop...
