Hello, ever since mob stacking has been added alot of peoples grinder will not work no more, I suggest there should be a menu when you right click a spawner that gives you the option to make it so mobs stack or dont stack. Also I suggest you add /friend, with this it can help you know when one of your friends come online. Personally I love the update, it reduces lag and allows you to afk farm with reduced lag. (for most cases) I got over 1000 sheep in a hour doing this and I got alot of wool and cooked mutton (as shown below)
