Help newbie: event warning when vassal is becoming disloyal

[unmerged(32150)]

I tried creating an event that would show a warning when my vassals loyalty drops below 20%, however it causes the game to crash.

###########################
# Vassal is very disloyal #
###########################

character_event = {
	id = 80000
	
	picture = "event_default"

	trigger = {
		condition = { 
			  type = is_vassal
		}
		condition = {
			type = not
			value = {
			      type = loyalty
			      value = 0.20
			}
		}
		condition = {
			type = liege
			condition = {
				type = not { type = ai }
			}
		}
	}

	mean_time_to_happen = {
		days = 1
	}

	action_a = {}
}

I also put these lines into the extra_text.csv:

EVT_80000_NAME;Vassal is very disloyal;;;;;;;;;;;X
ACTIONNAME80000A;Damn!;;;;;;;;;;;X

Apologies for a stupid question, but why doesn't it work?

I think there must be SOME action . Also, evets with only one choice AFAIK have immediate_action instead of action_a...

The event is triggered for the vassal, hence it works for the vassal but the liege does not see anything. You'll need to put in an effect triggering a second event for the liege.

Actions can be empty (the liege event should prolly have one).
