Cosmopolitan achievement - Bug or misunderstanding

[Cymsdale]

I've been waiting for this achievement to fire in my USA game for quite a while, and the ticking clock looks like it never will. I understand that some countries are locked out from this achievement from day one, but I don't believe USA is one of them. I have the highest acceptance modifiers and tons of cultures. What am I missing here? Are cultural communities somehow breaking things?

(Right now it says achievement not possible in current campaign, but it did not say that in the non-beta version.)

The current ingame description (wiki seems out of date, gonna fix that in a bit) says you need to start with 5 or fewer non-primary cultures, and USA has like 13.

(The definition of 'start' is unclear, Dutch East Indies also has more than 5 in 1836 but I got the achievement after changing to Indonesia)

EDIT: Also check real quick if you actually already have the achievement, I loaded a save after getting it and it also says 'not possible in current campaign'

Actually checked the script; the big thing is probably that the involved non-primary cultures (before and after) need to each be at least 1% of the population? (EDIT: Or the culture needs at least one pop that's 1% or more of its state's population? Or 1% of the total population of the culture in the country?)

achievement_cosmopolitan = {
    possible = {
        any_scope_culture = {
                NOT = {
                    is_primary_culture_of = root
                }
                any_scope_pop = {
                    filter = { state.owner = root }
                    pop_acceptance >= acceptance_status_5
                    percent >= 1
                }
                count <= 5
            }
    }
    happened = {
        custom_tooltip = {
            text = at_least_ten_acceptance_5_pops_tt
            any_scope_culture = {
                NOT = {
                    is_primary_culture_of = root
                }
                any_scope_pop = {
                    filter = { state.owner = root }
                    pop_acceptance >= acceptance_status_5
                    percent >= 1
                }
                count >= 10
            }
        }
    }
}

When is possible triggered?

achievement_cosmopolitan = {

                    is_primary_culture_of = root
                }
                any_scope_pop = {
                    filter = { state.owner = root }
                    pop_acceptance >= acceptance_status_5
                    percent >= 1
                }
                count <= 5
            }
    }
    happened = {
        custom_tooltip = {
            text = at_least_ten_acceptance_5_pops_tt
            any_scope_culture = {
                NOT = {
                    is_primary_culture_of = root
                }
                any_scope_pop = {
                    filter = { state.owner = root }
                    pop_acceptance >= acceptance_status_5
                    percent >= 1
                }
                count >= 10
            }
        }
    }
}

percent >= 1 means (at least) 100%. So the possible script reads: "5 or fewer cultures have 100% of their pops in owned states with full acceptance status" (including both culture and religion acceptance). Likewise, for the happened, just with "10 or more cultures"

When is possible triggered?

Possible should be checked "constantly" (probably just on game load/start). That is, if you passed Ethnostate, you'd probably be able to enable the achievement
