I built an Xp farm a few days ago, its a simple design and does not rely on a spawner. I know the rules about mob spawn and stuff, but it hasn't been working. The drop height is 22 blocks which should leave skeletons at 1/2 heart. But mobs never fall, and when they do it kills them. But that was at 24 block drop, ive moved it down but nothing happens. I need some help and advice from the community. I cant get a screenshot of it posted but if you guys could help me out there too I will post one. Thanks!
