The bug

The floor looks completely dishevelled after some time.

Minecraft intentionally will not tick chunks that are more than 128 blocks away from a player, so grass will not regrow. However, an entity can tick as long as its in an entity ticking chunk.

This problem has existed since 1.13.2.

Steps to reproduce

  1. Create a default Superflat world on Creative mode

  2. Ensure your render distance is at least 10

  3. Spawn a sheep 150 blocks away from you:

    /summon sheep ~ ~ ~150
  4. Fly directly upwards and use a spyglass to observe the sheep
    → ❌ Eventually, the sheep will eat the grass beneath it

Can confirm on vanilla 1.17 server. Minecraft doesn't spread grass in spawn chunks but entities still tick so sheep eat all the damm grass

Please provide a video with the debug screen enabled (hit the F3 key) demonstrating the issue.

I have been having this issue on my 1.19.4 Hardcore world. Looking over a map of the area shows massive patches of dirt blocks from sheep eating the grass, even though the area is 800+ blocks away. 

I have been going on slaughter sprees around my world to get rid of the sheep and stop it from causing issues with my performance

Here is a link to a clip from my twitch stream from yesterday where you can see the patches of grass that have turned to dirt outside of my loaded area. This is where sheep have been eating the grass even though the area is not loaded.

The changing of random ticking from occurring within 128 blocks of the player to occurring in all ticked chunks has effectively fixed this issue.
