Animals loosing intrest when you try to entice them up and down blocks.

There's this REALLY annoying bug where when you try to entice animals every time they jump up and down blocks they loose intrest. So it takes forever to get an animal to where you want it to go. note: They don't loose intrest randomly, it's only when you try to entice them up blocks, they just loose intrest when they jump up one block jumps while enticing them with wheat, carrots, seeds, ect. PLZ FIX!!!!
