hi everyone, i just started getting into modding rome total war. i kinda got the hang of it all after reading Epistolary Richard's guide for adding new units into the game. everything worked after i added a new unit, except for campaign. the new units even work in custom battle, but everytime i try to start a new campaign, it wont let me.

Since i added a new spartan unit into the game, i decided to play as the greek faction. so i choose greek and hit continue/next, but it just brings me back to the single player menu. would anyone know what might be wrong?

in custom battle, i chose every greek unit to play as, and they all work. other faction i just hit random and the game still loads properly. just campaign seems to not work. also, everytime i exit the game, a message pops up saying that i need to add two factions in the data/world/maps/campaign/imperial_campaign - descr_strat.txt i added the command "-show_err" to the rtw shortcut, which is how i got this message.

any help would be greatly appreciated, thanks!
