I have a house next to a fully walled in village with fenced in farm animals nearby. A few days ago when I returned to the area after exploring (only ten minutes away from the area) all of the villagers, farm animals, iron golems, village cats, tamed cats and tamed birds in the house had all disappeared completely. They never returned. I worked to replenish the farm animals, tamed cats and brought villagers from another village to that one. Then a day after establishing the villagers in their new village I logged in to find that they had all disappeared again. I started the process of bringing farm animals back to the area and when I logged in today I saw that once again they had all vanished. This seems to be a continuing pattern that I cannot escape.
