I don't know if thread necromancy is allowed but I tried to follow this https://www.twcenter.net/forums/show...ial-campaigns) to add the early campaign as a provincial campaign to a Stainless Steel submod. I edited the menu.int file as I was told and the menu part shows up fine but it crashes when I start it. I placed the relevant files in data/world/maps/campaign/custom/early_campaign and changed the name in descr_strat accordingly. The folder seems to have what it needs, I checked the provincial campaigns in Tierra Santa and tried to use them as a model (to see if any file was missing) but it doesn't look like that should be the case. The last post in the thread is someone having the same issue but that was many years ago.
Does anyone know what could be wrong?
