When making a cake, my milk buckets always lag. I click on a crafting table and click on "Cake" to automatically put the resources needed in. (I've tried putting the resources in manually, but the same thing always happens.) I then click on the cake to put it in my inventory, but then it goes to the crafting table interface. I click on it and it becomes the three buckets earlier needed for milk, and I click on them and they become the cake, etc. This never stops until I exit the crafting table and my buckets are empty again, meaning I have to go over and right-click on a cow again. 

This in its entirety means that I cannot make cakes, which is pretty annoying.
