In version 26.0, a new entity spawn trigger spawn_baby_jockey was added alongside spawn_adult and spawn_baby. However, zombie piglin jockeys spawned with this trigger cannot be picked up or transported by minecarts. This breaks many redstone contraptions that rely on minecart-based sorting or killing chambers, severely limiting player creativity and potentially causing massive entity buildup and world lag.
Observed Results:
A small percentage of Zombified Piglins spawn in a state where they are completely unable to enter any rideable entities, such as Boats and Minecarts. This is a persistent state that can be saved and re-loaded via Structure Blocks. Other mobs do not exhibit this issue.
Expected Results:
All Zombified Piglins should be able to enter vehicles.
1.Steps to Reproduce:
Set up a Command Block to repeatedly spawn Zombified Piglins in a 1x1 space.
Place an Activator Rail and a Minecart directly above the spawn point.
Power the rail to make the Minecart vibrate.
Normal Piglins will be picked up and ejected to the corner, but Bugged Piglins will remain at the spawn point, ignoring the vehicle.
Save the bugged Piglin with a Structure Block and reload it; the behavior persists.
2.otherway to reproduce:
Build the setup as shown:
Place an activated rail on top of a redstone block.
Place a minecart on the rail.
Surround the minecart with blocks (e.g., glass) on all four sides.
In the northeast corner, place a soul sand block, put a wither rose on top of it, and surround it with blocks to simulate a mob transport/killing system.
Spawn zombie piglins by right-clicking repeatedly with a zombie piglin spawn egg above the minecart. Observe that a very small proportion of them (approx. 75/10000) cannot enter the minecart.
3.or you can summon a zombie piglin with the spawn_baby_jockey trigger using the command:
/summon zombie_pigman ~ ~ ~ ~ ~ spawn_baby_jockey
Attempt to move the minecart or have the piglin enter it.
This bug still not fixing in the latest version.

Hm, okay, I can confirm this. I noticed that the broken piglins are missing the minecraft:pig_zombie_adult and minecraft:pig_zombie_calm component groups. This is strange for multiple reasons. It’s not clear why those component groups would be missing, since minecraft:entity_spawned should be guaranteed to add them. And it’s not clear why missing those component groups would prevent riding anything. But indeed, they have that effect – see MCPE-89988. Another effect of these broken piglins is that they don’t get angry when hurt, and they don’t drop experience when killed.
Thanks for reporting!
I think it is very important to fix this bug because it not only causes the device to slow down but also puts a huge performance pressure on the server. So please solve it as soon as possible.
This bug really, really affects normal operation - it causes zombie piglings to pile up too many in the machine, leading to lag and increasing the server load
