Impeachment of the Russian president doesn't work

[metroproxyn]

When the Impeachment procedure successfully went through the Duma and Senate, the following event runs:

country_event = { #Impeachment
    id = rusdem.107
    title = rusdem.107.t
    desc = rusdem.107.d
    fire_only_once = no
    is_triggered_only = yes

    option = {
        name = rusdem.107.a
        effect_tooltip = { retire_country_leader = yes }
        setup_ruling_party_president = yes
        remove_add_presidential_senators = yes
    }
}

However, neither the president retires nor the presidential senators are removed.
