The homeworld facility requirements is a top down list. It won't put more facilities on a planet then the planet can hold. If you have the sector type file setup so the planets have one facility space, then your homeworlds will have one facility, the first one on the list. There is nothing "wrong" with that change alone. I've made mods that restricted teh number of facility spots and had no poblems. Whatever is causing your error is something else. It might be the cargo thing. I've never tried setting cargo space to zero. Doesn't seem like that would be a problem though. Probably yo've made some other change by accident that's causing the error.
