Question is in the title, is there any mod that does this?
I won't update unless such mod exists since I have to have such utility. I like my mobs spread around so you gotta go to marshes for chickens or colder regions for your sheep or go out to plains to find cattle and so on. More spiders in deserts, more undead in cold places, more creepers in temperate regions. Slimes in the swamp, no natural witches except in spooky biomes, endermen bias towards dry biomes and so on as the squids cannot spawn anywhere but oceans. Don't even get me started on my modded mob spawn preferences, we will be here forever since I like BoP and any mob adding mob that doesn't have a totally out of place graphical style or adds in someone's fetish.
As mods have a bad habit of adding out of place mobs and it drives me insane to see a mob in a inappropriate biome. It actually causes physical pain to see it.
So is there a 1.11 mod that allows you to manage mob spawns yet? JAS hasn't had its port but JAS might not be the only such mod in that niche, any others?
