Across all of my worlds, in any game mode, any village, the villagers there all despawn overtime. Even when boxed into secure rooms, or walking about the village, none are safe from this bug, and this has been occurring ever since the Village and Pillage Update. This has happened over 4 different devices for me, around 6 different survival worlds I've had, and what truly upsets me is the worlds where I invest hours into building up a village with a full fence, full lighting, and such just for the villagers in it to despawn. I've tried over and over again but every time it ends in frustration as all my time has been wasted. Named villagers, villagers I've traded with, even a few baby villagers: They all despawn.
