apply_effect_bundle_to_region does NOT work.
Instead we must use: apply_effect_bundle_to_characters_force("etruscan_velzna_unrest",cqi,bundle_turns)
(bundle_key, region CQI, turns the bundle will be active (-1 for indefinite))
The way to get the CQI:
I'm getting the cqi from the colonel in the region (garrison leader) that I want. So I apply the bundle to his force.
Here's the code I'm using to get the CQI of a certain region:
And on my code I got these line to apply the bundle:
Hope this is helpful for any of you guys!
