Why there is an (extra) waiting time after the first completing of some missions?

[Lillebror]

Flags are often used in missions to prevent that a country can take a mission several times. Besides such use, one can find the following (example) code in several missions:

my_mission = {

    type = country
    ...
    allow = {
        ...
        OR = {
            NOT = { has_country_flag = had_my_mission }
            had_country_flag = { flag = had_my_mission days = 7300 }
        }
        NOT = { has_country_modifier = modifier_xy }
    }
    ...
    effect = {
        set_country_flag = had_my_mission
        add_country_modifier = {
            name = "modifier_xy"
            duration = 3650
        }
    }   
}

(Note: The granted modifiers are often used by several missions.)
What does this code do?
The code causes that between the first accomplishment and the second acceptance of this mission are at least 20 years. The waiting time for further missions solely depends on the modifier.

The OR-statement is also in some missions which don't grant a modifier as reward. There is then only a waiting time after the first fulfillment.

Is this what is intended? An extra waiting time after the first fulfillment of the mission?
Why?

Or else you can set youself up to shuffle between two missions for endless rewards.

It's called, the DDRJake effect. Many a change has come to the game via, presumably the devs, watching DDRJakes videos. Check out Ryukku #1, from a couple years ago now for endless mission swapping getting him to truly ridiculous levels of tech early game.

I see reasons why a country should not be able to take a mission more than once.
I see reasons why a country should have to wait some time before taking a mission again.

I still see no reason why there is a waiting time, respectively an extended waiting time, only after the first mission accomplish.

 

[Trin Tragula]

Yes its intentional some missions can't be taken again until some time has passed and some are once per campaign (most notably the extremely simple tutorial missions for new players such as "get a royal marriage").
Not sure what you mean with an "extra" waiting time though. There is one timer on the mission and an unrelated duration on the reward.
Once your reward has run out you can still get the same modifier from other missions, not just this one.

Edit: and as I missed part of the question the reasons are to preserve variety and to avoid cycling the same missions.

Okay. I try again with 2 concrete examples:

1.

recover_abysmal_prestige = {

    type = country

    category = ADM

    allow = {
        NOT = { prestige = -50 }
        OR = {
            NOT = { has_country_flag = recovered_abysmal_prestige }
            had_country_flag = { flag = recovered_abysmal_prestige days = 3650 }
        }
    }
    abort = {
    }
    success = {
        prestige = 0
    }
    chance = {
        factor = 1000
  
        modifier = {
            factor = 1.05
            is_at_war = yes
            has_idea = naval_glory
        }
        modifier = {
            factor = 1.05
            is_at_war = yes
            has_idea = glorious_arms
        }
        modifier = {
            factor = 1.05
            has_idea = patron_of_art
        }
        modifier = {
            factor = 1.05
            NOT = { stability = 1 }
        }  
        modifier = {
            factor = 1.05
            NOT = { stability = 3 }
        }  
    }
    effect = {
        add_stability = 1
        set_country_flag = recovered_abysmal_prestige
    }

}

If I have completed the mission the first time, I have to wait 3650 days before I could take it again. When I do so and complete the mission a second time, I haven't to wait again, as I have the flag already for at least 3650 days.

2.
I choose a mission which modifier and flag is used only by this mission.

improve_economical_mismanagement = {

   type = country

   category = ADM

   allow = {
     is_at_war = no
     num_of_loans = 10
     OR = {
       NOT = { has_country_flag = improved_economic_mismanagement }
       had_country_flag = { flag = improved_economic_mismanagement days = 7300 }
     }
     NOT = { has_country_modifier = impressed_financial_sector }
   }
   abort = {
     is_bankrupt = yes
   }
   success = {
     NOT = { num_of_loans = 1 }
   }
   chance = {
     factor = 1000
     modifier = {
       factor = 1.05
       adm = 2
     }
   }
   effect = {
     set_country_flag = improved_economic_mismanagement
     add_country_modifier = {
       name = "impressed_financial_sector"
       duration = 3650
     }
   }
}

If I have completed the mission the first time, I have to wait 7300 days before I could take it again. When I do so and complete the mission a second time, I have to wait 3650 days before I could take it again.

Why there is a waiting time, respectively an extended waiting time, only after the first mission accomplish?

As the first example shows, a fast repeat is prevented only after the first time.

Lol that DDRJake guy was one hell of a betatester

Did you try that? Because seting the flag again if you already have it resets the "has had it for x days" last i checked
Can't check now though as I'm not working (parental leave).

No. Just read the code. Didn't know that.
I will check it by playing.

Edit:
Checked.
It is also in the Wiki:

had_country_flag - Clause - Returns true if country flag X was last set for country at least Y days ago

@Trin Tragula: Thanks for you patience.

Congratulations!!
