Two Quick Modding Questions

[shatner]

Alright, I got another question: how do you make national spells for a nation no longer available? Specifically, for the MA Jomon mod Legowarrior and I are working on, I need to redefine LA Jomon to be MA Jomon. However, MA Jomon isn't supposed to have access to all the oni and undead summoning national spells (just the kami summoning ones).

First I tried selecting all the offending spells and adding #restricted statements to make it restricted to just Shinuyama and, when applicable, Yomi. That didn't work.

The mod documentation said a spell can only have 3 such restrictions so secondly I tried restricting those spells to Shinuyama, Yomi when applicable, and then one or two unused nations (nations 23 and 24 which are "AI Special Monsters"), in an effort to push LA Jomon out of the three nations a spell can be restricted to. That didn't work.

Third, and finally, I tried copying all the spells and setting those copies to be restricted to just Shinuyama and Yomi. Then I modded all the original spells to be unresearchable (#school -1). That didn't work.

Is this something you can do when modding Dom3 and, if so, how? Thanks in advance for any replies.
