I started a new world when the Village & Pillage update came out, immediately found a village and started work. But I noticed when I was nearing completion of the renovations that all of my villagers have stopped using their beds & homes alike. I thought I had just messed up the village by moving everything around, so I started a new world. I was careful when I found this new village to not alter any existing structures and instead just built a wall around the village. But as I completed my wall, I noticed once again my villagers have stopped using their beds and houses. In this case all but one of my villagers also disappeared.
