Potential problem with Crusade CB

[richvh]

In the Crusade CB's on_success_title section, there is a culture=PREV where the PREV resolves (as far as I can tell) to the claimed title, and according to my tests culture = <title scope> doesn't work.

This is the section in question, up to the problem point:

	on_success_title = {
		if = {
			limit = {
				has_holder = yes
				holder_scope = {
					religion = ROOT
				}
			}
			holder_scope = {
				gain_settlements_under_title = {
					title = PREV
					enemy = FROM
					is_crusade = yes # Even if the title holder is not participating in the war, gain holdings occupied by all Crusade participants
				}
			}
		}
		
		if = {
			limit = {
				OR = {
					has_holder = no
					NOT = {
						holder_scope = {
							religion = ROOT
						}
					}
				}
			}
			
			most_participating_attacker = {
				gain_settlements_under_title = {
					title = PREV
					enemy = FROM
				}
				if  = {
					limit = {
						primary_title = { is_primary_type_title = no } # Mercs, the Pope, Holy Orders, etc
						PREV = { has_holder = no }
						OR = {
							NOT = { character = ROOT }
							independent = yes
							liege = {
								tier = EMPEROR
							}
						}
					}
					usurp_title = PREV
					
					if = {
						limit = {
							[COLOR="#FF0000"]NOT = { culture = PREV }[/COLOR]                          #<-Problem point, PREV resolving to on_success_title
						}
						hidden_tooltip = { PREV = { conquest_culture = THIS } }
					}
				}
			}
		}

What I think it ought to be (though I'm not confident that ROOT won't still resolve to a title scope):

	on_success_title = {
		if = {
			limit = {
				has_holder = yes
				holder_scope = {
					religion = ROOT
				}
			}
			holder_scope = {
				gain_settlements_under_title = {
					title = PREV
					enemy = FROM
					is_crusade = yes # Even if the title holder is not participating in the war, gain holdings occupied by all Crusade participants
				}
			}
		}
		
		if = {
			limit = {
				OR = {
					has_holder = no
					NOT = {
						holder_scope = {
							religion = ROOT
						}
					}
				}
			}
			
			most_participating_attacker = {
				gain_settlements_under_title = {
					title = PREV
					enemy = FROM
				}
				if  = {
					limit = {
						primary_title = { is_primary_type_title = no } # Mercs, the Pope, Holy Orders, etc
						PREV = { has_holder = no }
						OR = {
							NOT = { character = ROOT }
							independent = yes
							liege = {
								tier = EMPEROR
							}
						}
					}
					usurp_title = PREV
					
					if = {
						limit = {
							[COLOR="#0000FF"]NOT = { culture = ROOT }[/COLOR]
						}
						hidden_tooltip = { PREV = { conquest_culture = THIS } }
					}
				}
			}
		}
