The UK Focus "Burma Road" is coded incorrectly

[Bridger15]

I've always been confused as to why this focus is so useless, as the in-game tooltip only shows that it causes some news events to fire and some opinion modifiers to change. I decided to improve it's effects in my mod, but when i dug into the code I found this part of the focus (which has never shown up in tooltips)

completion_reward = {
            640 = {
                if = {
                    limit = { is_controlled_by = ROOT }
                    add_building_construction = {
                        type = infrastructure
                        level = 2
                        instant_build = yes
                    }
                    add_building_construction = {
                        type = air_base
                        level = 2
                        instant_build = yes
                    }
                }
            }
            325 = {
                if = {
                    limit = { is_controlled_by = ROOT }
                    add_building_construction = {
                        type = infrastructure
                        level = 2
                        instant_build = yes
                    }
                    add_building_construction = {
                        type = air_base
                        level = 2
                        instant_build = yes
                    }
                }
            }
            601 = {
                if = {
                    limit = { is_controlled_by = ROOT }
                    add_building_construction = {
                        type = infrastructure
                        level = 2
                        instant_build = yes
                    }
                    add_building_construction = {
                        type = air_base
                        level = 1
                        instant_build = yes
                    }
                    add_extra_state_shared_building_slots = 1
                    add_building_construction = {
                        type = arms_factory
                        level = 1
                        instant_build = yes
                    }
                }
            }

The problem is that this is coded so that these effects will fire if ENG controls them (as it is an ENG focus, so ENG is the ROOT). However, they start in control of either RAJ or China or Yunan. They will never reasonably be controlled by ENG.

Here's how I fixed it:

completion_reward = {
            640 = {
                if = {
                    limit = {
                        OR = {
                            ENG = { controls_state = 640 }
                            any_other_country = {
                                is_in_faction_with = ENG
                                controls_state = 640
                            }
                        }
                    }
                    add_building_construction = {
                        type = infrastructure
                        level = 2
                        instant_build = yes
                    }
                    add_building_construction = {
                        type = air_base
                        level = 2
                        instant_build = yes
                    }
                }
            }
            325 = {
                if = {
                    limit = {
                        OR = {
                            CHI = { controls_state = 325 }
                            any_other_country = {
                                is_in_faction_with = CHI
                                controls_state = 325
                            }
                        }
                    }
                    add_building_construction = {
                        type = infrastructure
                        level = 2

                    add_building_construction = {
                        type = air_base
                        level = 2
                        instant_build = yes
                    }
                }
            }
            601 = {
                if = {
                    limit = {
                        OR = {
                            CHI = { controls_state = 601 }
                            any_other_country = {
                                is_in_faction_with = CHI
                                controls_state = 601
                            }
                        }

                    add_extra_state_shared_building_slots = 1
                    add_building_construction = {
                        type = arms_factory
                        level = 1
                        instant_build = yes

                }
