Overpopulation
 

Is there a way to make a nation automatically increase its population without having to alter the growth scales? Also, is it possible to set the growth rate to even higher levels? I have a plan for a mod that involves some tree-dwelling, white-furred rodent people whose units all have domsummon20, and have to use magic and/or expand rapidly in order to be able to get enough food. Most of the units will be small, size one, stealthy units, who will have, to mitiagate the food shortage, forest survival skills, even though this won't be enough to totally solve any food problem. An extreme example of rapid population growth would be 20% per turn http://forum.shrapnelgames.com/images/smilies/eek.gif , but I don't know if the a province could actually hold that many people.

P.S. The white furry rodent-people will have spears and javelins, and some of them will have poisioned spears/ throwing spears.

You should give all the commanders all of #domsummon2, #domsummon and #domsummon20. It still won't matter much, but it will actually create lots of units. Also, #domsummon20 is one twentieth (1/20) as effective as #domsummon, not twenty times as effective as #domsummon...
You can #copystats Panii of Pangaea and use #clearmagic to remove their magic. You can change their normal stats and size to you want, and you're left with a creature that has Stealth, Forest Survival, Recuperation... and the special ability to attract Maenads in turmoil dominion. It would be easy to change Maenads into something of about equal power that both Pangaea and your new nation would summon.
Pangaea also has access to nation-spesific reanimations and Carrion Woods the global.

You don't actually want Growth scale, but supply bonus. You could give all the commanders supply bonus. That way, they can feed the armies for a few turns, but making more commanders to feed the current army would lead to even faster increase in supply use...

Small units (size 1) won't eat much supplies, so you might have to change the nation so that it also has bigger, a bit more rare (size 2, 3 and maybe 4) units that are essential to its army. That way, the need for supplies will rise faster.
