Client crashes on shutdown with Watchdog timeout (Baritone CachedWorld$PackerThread hang)[Bug] #6674
Description
Describe the bug
When quitting the game, the client hangs on shutdown and eventually crashes with java.lang.Error: Watchdog (Client shutdown from post-main).
According to the thread dump in the crash log, Baritone's background world caching threads (baritone.cache.CachedWorld$PackerThread) stay active saving region files and fail to terminate before the Minecraft client's shutdown watchdog timer expires.
Steps to reproduce
- Launch the game with Meteor Client / Baritone loaded.
- Join a world or server so Baritone initializes world caching threads in the background.
- Save and quit or close the client.
- Observe the client hanging on shutdown for ~30 seconds until the Watchdog forces a crash.

This doesn't look like a Meteor related crash, it's an issue that was supposedly fixed in Baritone already here: cabaletta/baritone#5123.
It has yet to be ported to the other versions so we can't do much about this.

Have you patched this error?

Interesting. Same thing has been happening to me. Going to take a look at this.

Seriously. A reality is that only this 26.2 update have so many bugs and errors that any other versions ever released before 26.1.2 and below.
Maybe if they will fix this error in this update or update it in next 26.3 update.

I second what @Big-Iron-Cheems is saying. This is a baritone error. It's not even a crash as such. It's just the minecraft client forcibly terminating a hung JVM.

Have you patched this error in this version of meteor client?
Big-Iron-Cheems commentedon Oct 10, 2026
I think I made it clear the first time that this is a Baritone issue, not a Meteor one.
There's nothing we can do on our end to address this.

What about the meteor baritone fork? that may have not been patched yet?
I shall take a look
