I have 2 regions that are unpopulated "High Desert" aka (Klamath Falls) and "Coastal Range aka (Eureka). The names in () are from the database of region names the game uses.
I keep trying with different script variations but northing ever happens. I did get a parsing error in the logs when I was using the region names from the game. Here are the 2 scripts I used last turn (turn 5 of year 1959)
SelectFaction = $USA
SelectRegion = $Eureka
SelectFaction = $USA
SelectRegion = $Eureka
StartEvent = evt_nam_USA_CoastalImmigration1859|1|1|NULL|NULL|$Eureka|NULL
Conditions
MinDate = 1850/01/01
MaxDate = 1863/12/31
EvalRgnOwned = $Klamath Falls
Probability = 100EvalRgnOwned = $Eureka
Probability = 100
Actions
DescEvent = evt_desc_USA_CoastalImmigration1859
SelectRegion = $Eureka
ChgPopAristos = 1
ChgPopUpper = 1
ChgPopMiddle = 1
ChgPopWorkers = 10
ChgPopPeasants = 20
EndEvent
