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:
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.
What I expected to happen was...:
Things should NOT disappear
What actually happened was...:
First, all of my pigs disappeared. After a raid, items in my house disappeared. Now villagers are disappearing.
Steps to Reproduce:
1. Whenever I leave my village and return, new things have disappeared.
