How do you do it? What I've been doing is "installing the mod", then opening TibEd, but none of the new units show up, and if I make/save changes and play the game, it's the original units.
Is there a way I can mod a mod?
EDIT: Nevermind, I forgot about the XCC Mixer Tools, I'd assume all I need to do it open the expandmd04.mix and edit the rulesmd.ini file.
