      The bug

      Sometimes, entities can disappear upon reloading the world. Players have reported that this is happening to animals, villagers, item frames, armor stands, and other entities.

      KaptainWutax has investigated this a bunch, and he believes he understands the cause. Quoting him:

      Tons of people are reporting to me that their villagers are disappearing in their iron farms. The error is ALWAYS a position desync, of this format:

      Wrong location! (-65, 4) should be (-54, 13), avk['Villager'/172716, l='world', x=-1037.30, y=89.00, z=70.30]

      Some are related to sleeping on chunk borders (reproduceable consistently), and some seem completely random, in the center of chunks.

      Here's a link to a video of the reproducible occurrence: https://streamable.com/0ivkh

      The easiest way to reproduce this bug is to push a villager slightly out if its bed while it is sleeping, so that its hitbox now is across a chunk border (as seen in the video linked above). However, this issue can also occur in other circumstances.
