I have been using Duke of Serbia's guide to make a new faction. Unfortunately after I did all the steps, my faction did not appear the list of playable factions at the Grand Campaign menu. Than when I try to play any of the other factions, it just goes back to the Single Player Menu. When I restore the files I changed to their originals, it goes back to normal. :hmmm:
I have gone through the steps and have found no mistakes. If you have any idea how to fix I would love to hear it, especially from Duke being his tutorial. Thanks.
Here are the files that I changed. My faction is called romans with The Roman Empire being its campaign name. Hope this helps.
And here is some more...
And the rest.
