I just got my lil cow last night! :D The cup originally spawned on the top level of the barn, I could see it thru the opening. But I logged out and went to another character. Checked on her followers and their missions, came back to the toon with the barn. And there on the ground floor, on top of some boxes by the cups and plates, was my cup of warm milk!!! No need to switch my buildings around! ;)
