I'm trying to get the light infantry doctrine available at the military academy rather than the army board, because I think light infantry arrive too late in the game.
Using the latest version of pack file manager I've created a new pack as a mod and changed the technologies file in the db/technologies_tables folder from the exported files from main.pack, so that the military_army_light_infantry_doctrine building prerequisite ID Ref column is changed to military_academy.
However when I load a campaign or start a new one the icon for the light infantry doctrine does not show up. Is there something else I should be changing? I'm creating this as a mod file for use with the Mod Manager tool.
All my other mods work using the same proceedures, where I've modded textures, sounds, weapon ranges etc, so I'm thinking I've missed something.
Thanks for any help.
