I want to try making the holy city missionaries used in my mod as a modular component, but the game fails to load these files on startup. I get an error message that simply says, "Failed to load X", but it unhelpfully doesn't tell me why. The units are all in one file, use existing artdefs and even existing unitclasses. So I only have the UnitInfos file and the UnitSchema file. They're named with the X_Civ4UnitInfos.xml style, and I changed the schema line of the unitinfo file to point to the right file. But on load it just says, "Failed to load X." Any help on how to do this?
