Hi, I'm looking for a way to automatically dispose of any extra/unwanted mobs in my farming system. I have them contained readily deliverable to a killing room, but am unable to actually kill them without hitting them myself. To stop them from building up and eventually cease spawning, I need some of them to die. Any ideas how? Cactus and lava do not work, nor does drowning or suffocating. Is there a flag I need to kill them? Thanks!
