In RTW I could make unit cards as I created a UI folder in the data section. I placed my unit cards inside that UI folder and they worked.

But with BI, there is already a UI folder containing all of the unit cards. So I put my new unit card into the appropriate factions section of it, but it doesn't come up in game. Does anyone know how to fix this?

Any help would be really appreciated as I'm working solo on a mod just-now and this is holding me back.
