Adding Kingdom things to a M2TW mod

[Imperator_Maximus]

I have just gotten Kingdoms and one of the first things I want to do is add some of the neat stuff into my mod. First I'm having trouble adding in the new Byzantium units to my mod. When I try adding Pronoia Infantry, this error keeps appearing.

I put the meshes and sprites and I'm sure I put the Pronoia lines into the battle_models file correctly. Ideas?

Also, how to you add in some of the game features of the campaigns into the grand one, like pernament forts and stuff?
