If a zombified piglin has been tracking a turtle egg, it will continue to track it even if moved more than 24 blocks away from said egg. Even with a secondary turtle egg within 10 blocks they won't stop tracking the one 26 blocks above them. When reloading the game, it fixes itself.

Steps to reproduce

1. Place a turtle egg and spawn a zombified piglin next to it
2. After the zombified piglin targets the egg, run the following command:

   /execute as @e[type=minecraft:zombified_piglin] run tp ~ ~ ~40
