private Type type;

public Nation(Type type){
//stuff
this.type = type;
}

creating the object:

Nation gaul = new Nation(Type.SWAMP);

Leads to the following exception:

[10:27:40] [Server thread/ERROR]: Error occurred while enabling nationsatwar v1.1 (Is it up to date?)
java.lang.IllegalArgumentException: The validated object is null

        at net.mcnations.nationsatwar.general.packets.npcs.Architect.spawnEntity(Architect.java:108) ~[?:?]

line 108 in the Architect class is the following:

architectVillager.setVillagerType(nation.getBiomeType());

When I print biomeType in the constructor, it is null. As we can see, it is clearly NOT null when being passed into the constructor (Type.SWAMP). However, when I type Type.SWAMP as a constant inside the constructor, it works - no errors.
