I've figured out how to increase mod mob health to more TFC like levels with Mob Properties, and now I'm looking for something to help spawn mobs from other mods to TFC. The only place I've seen Just Another Spawner mentioned is in the Terrafirmapunk discussion. I muddled through that thread a bit, but didn't see an answer to the question I have. To anyone with some experience with JAS, does it seem to change the TFC spawning in any noticeable way? My specific concern would be that it might change tameable mob (cows, pigs, chickens, etc) spawns from only at chunk gen (with no despawn) to standard vanilla spawning and despawning. Also, now that I think about it, does JAS happen to change the way mobs spawn related to temp? I remember reading somewhere the TFC bases spawns on temp and biome. The further north you go the less tameable farm animals you'll see and the more wolves, deer, and bears you'll run into for example.
