Now, before anything else, I'd like to say that I know that there are a couple of amazing "how to install leaderheads" tutorials around, and I have checked them and followed the instructions to the letter, modding all the .xml files [except the schema stuff, they said it wasn't needed], and I did it both in the "custom assets" folder, the regular game folder, and even the vanilla Civ4 folder [I was starting to despair by that point].The problem is... the leaderheads DON'T appear on the game menu. I know it has something to do with BAT, though, because when I uninstall/unload it, they do appear! 
How can I fix this? It pains me not being able to use all those awesome leaderheads in my game.
P.S.: I use Bat 2.1
P.P.S.: Thanks in advance, guys
