The bug
Ghastlings get stuck in the void when pathfinding below the world’s height limit. This is not the case with happy ghasts.
How to reproduce
Create a void world.
Summon a ghastling.
/summon minecraft:happy_ghast ~ ~ ~ {Age:-12000}
Tempt it with a snowball to below height limit while in creative.
While below height limit, stop tempting it.
Notice the ghastling pathfinding.
Expected result
The ghastling would continue flying around below the height limit.
Observed result
The ghastling is now stuck, frozen in the void.
