[MCPE-222147] Happy ghast causes extreme lag

When a happy ghast’s bottom fully touches the ground it causes really bad tps lag.

Steps to reproduce:

Spawn a happy ghast
Get it in an area where it is forced to touch the ground to the point where you can’t see its tentacles
Place a fence 2-3 blocks below that happy ghast
Leash the happy ghast to that fence
Try breaking blocks, dropping items, or watching mobs move
observed results: really bad lag
expected results: no lag

Managed to recreate the issue. Seems to happen more often with fences but it also happens with regular blocks.

Lo confirmo. En Android pasa lo mismo. El Happy Ghast causa mucho lag cuando esta presente en un chunk cargado.

crystalpart 2025-06-19T16:48:49Z

Yep! same thing happens to me. i have a video too but it won't send

Purlynx 2025-06-20T14:22:57Z

Yeah, it happens when bottom of the leashed Happy Ghast (either by fence or player) touch the ground.

malarkey42 2025-06-21T04:09:48Z

I can confirm, it lags so bad that I can’t even place or break blocks. Everything stops working because of the happy ghast on lead.

De La Cupertino 2025-06-21T07:06:39Z

Definitivamente lo mismo me sucede a mí. El happy ghast causa congelamientos y mucho lag cuando el se esta cerca del happy ghast.

Tied to a lead, when the happy ghast is touching the ground in its idle state, TPS immediately tanks. It’s really bad.

Observed TPS drop when the bottom of the ghast touches the ground:

Hi, my world starts lag when I trap the happy ghast in a fence too.

Kezha 2025-06-23T03:30:49Z

Here’s what I’ve noticed: I've encountered this while playing solo and offline so I don't think it's a network/internet issue. I imagine this occurs online and in multiplayer too.

I’ve stopped leashing my Happy Ghast near my base since I noticed this issue and I'm no longer experiencing drops on TPS. I recommend avoiding leashing to a fencepost as a workaround until this bug is resolved!

Thanks Ryan Magner for the tip

CitrusFruit 2025-06-25T16:12:14Z

This is triggered by the ghast touching the ground

Santiago Mejía Florez 2025-06-25T22:25:39Z

The same thing happened to me, my solution was to kill the Happy Ghast, I hope they fix the bug so I can have Happy Ghast in my base

anderjohanneskaaramees 2025-06-26T08:07:09Z

I have same problem. I putted happy ghast in the minecart and then lag stopped

Dark_Julian0000 2025-06-27T07:13:56Z

It lagged for me when i parked it at a wooden crane xD

Jay P 2025-06-27T16:44:51Z

Have this issue also we have 3 happy ghasts on the realm and it brought so much lag that you brake blocks and then watch them take up to 5 seconds to hit the ground.

putting happy ghasts in mine carts has helped a lot luckily found that work around before killing them.

IBdaNOman 2025-06-28T01:23:00Z

This issue seems to be significant when the happy ghast is touching the ground. With everyone having happy ghasts this need sto be fixed.

Papa Brandus 2025-06-29T10:28:35Z

We are not playing at an i5-4590. It is’t playable.

One client at Android-Tablet may be ok. I play slowly, because I'm an old player. With two players it is too laggy. Broken blocks fall slowly after a short break.

Please fix.

My server also encountered this situation. At that time, there was a happy ghasts in my server. When it landed, the TPS of the entire server dropped from 20 to 2 instantly.

This was the situation at that time.
