The check is performed in net.minecraft.world.level.block.entity.trialspawner.TrialSpawner:

public boolean canSpawnInLevel(Level world) {
        return this.overridePeacefulAndMobSpawnRule
            || world.getDifficulty() != Difficulty.PEACEFULL && world.getGameRules().getBoolean(GameRules.RULE_DOMOBSPAWNING);
    }

This issue has been fixed. To get the fix, you need to restart your Minecraft launcher. It will perform a background library update. If afterwards you still have a connection issue, please make another ticket.

Hi Mike, 🙂

For splash text concerns and suggestions, feel free to go to the Official Feedback Website.

@@unknown Nothing is wrong with your keyboard. With the faulty library now updated, this issue is fixed starting in 1.19. 🙂

Unfortunately, if you are on 1.17 or 1.16, you will still be experiencing MC-218167 (one-time stuttering). You will need to update to the latest game version in order to get this issue fixed. If you appear to still have the one-time stuttering chat issue in 1.18, please make a new ticket in MC project.

However, if you used to have multiple stuttering issues (this ticket) that appeared recently, you should now see improvements whether you are running 1.16, 1.17 or 1.18.

@@unknown That's a completely different issue that was fixed in the latest version, and unfortunately older versions are retroactively not supported.

@@unknown This is correct, although not a workaround, just the normal behavior is that accounts fetch their information at startup. Please feel free to make another ticket in the MC project for the underlying network blocking issue.

This issue was not initially caused by Minecraft but by its underlying web services that accounts depend on in order to function. This is why it should be fixed whatever game version you are currently running.

The cause of this issue is known. No need to post any additional comment. 😉

Hello @@unknown,

For some reason, your game folders are in read-only mode. This is why you are not able to delete the world. Changing folders permissions will simply fix your issue. If you need assistance, please see with the Minecraft Community Support discord. 😉

Hello @@unknown,

It looks like something is causing lag with your modded GUI. Unfortunately, we can't provide help with a modded version of the game here. Please see with the mods creators (check your mod if you are the creator) or your API library. Additionally, if you can reproduce this issue in vanilla, feel free to open a new issue. 🙂

Thank you for your report!
However, this issue is Invalid.

Performance drops are expected to happen between versions. Simply stating that "My game is laggier" is not helpful for Mojang to diagnose your issue. If you can pinpoint a specific cause when lag happens for you, please open a new report for that specific issue.

Keep in mind that Mojang is constantly optimizing the game and simply playing the game provides feedback to Mojang on which parts cause performance issues. To learn more about this, head here (section "Telemetry") for more information.

Hello @@unknown,

As far as I know, these “stone walls” are perfectly normal with the new cave generation and can be seen around often. However, if you think this is something that should be changed, feel free to make a suggestion on the Feedback website. 🙂

Do you mean about the grass spreading inside the cave?

@@unknown As far as I know, this is a normal world generation feature and not a bug. However, if you think this should be modified somehow, feel free to leave a suggestion on the feedback website. 😉

That's correct. @@unknown Advancements will only show up after you got the first one. 😉

Hello, I'm unable to reproduce this issue. I'd suggest you to join the Minecraft Commands discord server if you need more assistance with the scoreboard. 🙂

Mojang does not develop Paper. Only comment if you are able to repro with the official server jar.

Can confirm to be fixed as per the given repro steps.
