Eometheous

Can confirm for 2.4.4 (Mac)
I'm on macOS Ventura 13.2.1 with the M1 Pro chip.

Hello! I was not able to reproduce this issue :/
I defeated the Ender Dragon twice and there are two end gateways.

I can confirm, I tried running the launcher after installing on my new MacBook Pro and it is requiring me to install Rosetta in order to open the Minecraft Launcher.

Still happens in 1.19 RC1

Wasn't able to reproduce.

I know MC-249393 was resolved as won't fix which describes the issue with the warden digging down right away.

By editing your command slightly I can get it to not dig into the ground.

/summon minecraft:cow ~ ~ ~ {Passengers:[{id:"minecraft:warden",Brain:{memories:{"minecraft:dig_cooldown":{value: {}, ttl: 1200L}}}}]}

To stop it from getting angry at the cow it is riding, I can set them to the same team.
First create a team

/team add warden
/team modify warden friendlyFire false

Now we can summon a warden riding a cow while being on the same team with each other with the following command

/summon minecraft:cow ~ ~ ~ {Team:"warden",Passengers:[{id:"minecraft:warden",Team:"warden",Brain:{memories:{"minecraft:dig_cooldown":{value: {}, ttl: 1200L}}}}]}

I wasn't able to reproduce this. I could only add the swift sneak enchantment to leggings as expected. From the looks of that screenshot, you are in creative mode. I don't see any hearts, hunger, or experience bar above the hotbar.

Here is this behavior happening when I am just 48 blocks away.

1. Summon a warden

2. /tp @s ~-48 ~ ~ -90 0

3. Wait some time (it's random so it can take some time, I found that setting the time to night made if faster since more mobs were spawning)

Observed Results:

The warden despawned

Expected Results:
The Warden should only despawn when digging into the ground.

@[Mojang] Grum (Erik Broes). These are the steps to reproduce:

1. Summon a warden

2. /tp @s ~-130 ~ ~ -90 0

3. /tp @s ~130 ~ ~ -90 0 (Or you can just fly back to where the warden was summoned)

Here is a video showing these steps

Observed Results:
The warden has despawned immediately because the warden is over 128 blocks away.
It can also despawn randomly if it is in between 32 blocks and 128 blocks away as seen in the picture above.

Expected Results:
The Warden should only despawn when digging into the ground.

Can confirm in 22w18a. Found these when looking for submerged ancient cities.

Seed: -4958260856419505585

Location: /tp @s 42355 -46 -24555 -90 10

Can confirm not fixed. Creating a new world with the original seed (-4958260856419505585), I still managed to find ancient cities that were getting submerged in aquifers.

/tp @s 1669 -33 -16758 120 30

@Markku, if you are on windows, you might have the XBOX Game Bar App. You can record a short 30 second clip with by pressing the windows key and G at the same time and then click on the record last 30s button on the top left. Or you can press the window key, alt key, and G at the same time.

Do you have hostile creature sounds turned off?

Could you attach a crash report? There is a folder called crash-reports in the .minecraft folder.

I'm not sure if you are experiencing this from MC-250954 or not.

That bug only happens in singleplayer, but it might be happening in LAN as well? However, it's strange that you lost your items and started at spawn. Since MC-250954 only seemed to reset statistics and achievements.

Happens in 1.18.2 as well.

I just tested this in my snapshot server. I was able to get a crash report from there.
Here is the crash report.

This time it closed automatically with this error code.

Here is the launcher log

@violine1101 a crash report wasn't created when the game crashed. I did get an error code though.

Process crashed with exit code -805306369

Here is what Reliability History says about the crash

Here is what event viewer says about the crash
