I am about to make some cake, all I need are 3 buckets of milk. So I go to a friend's home and go to his cow farm, get the
stuff and teleport back home. Right when I right click on the crafting table, the milk in the buckets disappear and the buckets are regrouped into a stack. I /helpop and the mod AwesomeAlica tells me to relog on, I do so because that will fix some bugs instantly. I did so, tried again and no, didn't work. Please if a operator or owner could read and fix this, I would greatly appreciate it.        

By best guess is server lag. Sometimes similar things will happen such as taking items from a chest, but later find them back in the chest because of server lag.

That kept happening to me.  I was milking a top voter's cow, then I teleported home and the milk disappeared from my buckets.  Then I got him to milk the cows and the milk didn't disappear when he milked it.

This happens many times, and it will happen again. There is nothing you can do to stop it, it happens randomly.
