If you mean the resurrection thing, its the regional interactions i cooked up:
http://dffd.bay12games.com/file.php?id=13714Fair warning, that resurrection issue extends to shorn wool from animals and stuff, too, so butchering or shearing sheep in a resurrecting biome could result in infinite sheep popping up. Animals like horses also drop a hair item when butchered, which also gets resurrected. Enemies and wild animals will also respawn with the same hatred for you as beforehand (potentially more?) but domestic animals that resurrect are listed as friendly, but not tame, and can be targeted by the militia but not caught in cages or otherwise captured/pastured. Gods, ive got to fix that stupid thing, it was honestly just a side project at first to see what else could be done with regional interactions, and its horribly broken now.
The war polar bears, iirc theyre war trainable by default? But i changed my dwarf entity to let me have lots of weird animals. Requires adding creature classes to all the creatures you want to be eligible and then allowing the entity to tame anything of that class if available in their environment.
But you cant just use the general_poison creature class, or youll be able to embark not only with people but megabeasts and some nightcreatures, which will still be hostile to everyone. All it takes is a migrant wave to show up with a "pet" dragon.
I played on that save for a while but then the game crashed. In that time i had a nosferatu outbreak due to opening the caverns. Anything killed would resurrect, and since nosferatuism is a form of contagious, berserk-causing transformative vampirism that meant never ending vampire zombie apocalypse, which is probably why the game crashed... Thats another thing ive got to work on. Spellcrafts mod for the nosferatu thing btw...
