Hello, I'm currently trying to run an RPG server with raids and such. I'm trying to remove mob spawning in a certain world but allow mob spawning through mob spawners. So basically, I want to disable natural mob spawning but allow mobs to come out of mob spawners. Thanks guys and girls!
I've been looking for one as well and I ran across this. Haven't tested it yet but it looks good. http://dev.bukkit.org/server-mods/mobsuparemoval/
