Well hell, that might make sheep farming more efficient. What I'm not clear on is if you grow wheat in their pen and they eat it, making the cycle more automatic, or if you have to feed them wheat manually.
Btw, do note blocks work anymore? One thing I've noticed while taking a ride on the rail is that it no longer chimes like it used to.
Dunno about wheat. We'll have to wait for the official update I guess.
I think one of the updates changed the physics of redstone. I'll need to go digging and see whats going on under the stations.
