In rimworld, There is an issue where pawns that come in event or quests are forcibly changed to vanilla pawns type even though they are mod factions.
* This mod solves event / quest pawn issues for
all of mod human/non-human factions, vanilla expended faction, races added as human alien races, and races added as garam races.
* So you can meet real faction pawns added as mods in various situations.
