Also, I tried under Galactic Conquest using the "<Special_Case_Production>" line that the Cantina and Hutt Palace uses. Still no luck!
I also wanted the Empire to only be able to build StarBases on Core Planets. I used the <Required_Planets> line but that did not work, either.
EDIT: Problem solved by using the <Required_Planets> line, it just wasn't saving properly.
