I was filling some water pads, with water and speed filling is so easy, with jumping to the next free spot in my inventory, so with one free slot a split a stack of item so that the bucket would have to go in the slot, it came from, no it just disappeared, so then I had to make another, and by time I went back to my farm, I had full inventory, and not think guess what another bucket gone.
