This bug is still present in version 1.20.10/1/2.
I have put a version of the add-on with the entity that appears in the test video and the textures. In case it is necessary.
For the entity to execute the eat event, you put this command: "/event entity @e[type=piglin_brute] ha:start_regenerate". You may need to put it more than once.
In the PC or Windows 10.
All right, I've already put it.
Requires the experimentals: "Holiday Creator Features, Custom Biomes and Beta APIs".
It was fixed in 1.16, so no problem
No, this has already been resolved and works perfectly in the current version of the game (1.20.40/1). Although I am unaware of in which update this was already fixed.
