I have repeatedly put the game in and out of peaceful mode, I have moved villagers in various areas across my world, confined them into boxes/houses of all types. Even built walls around villages in and out of peaceful fully lit and have found one common error and that is when I am within radius they just disappear sometimes when I sleep in bed and sometimes I have just turned my back to turn around and they have disappeared. I am not finding any other mobs disappear just villagers.
