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
Place a turtle egg and spawn a zombified piglin next to it
After the zombified piglin targets the egg, run the following command:
/execute as @e[type=minecraft:zombified_piglin] run tp ~ ~ ~40
Can confirm in 24w45a. Also would like to request ownership of this report to maintain it/update the description to provide steps to reproduce.
