Bundle Crash Fix
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Bundle Crash Fix
Protect yourself from nasty cheaters trying to crash the server with Bundles!
Paper has fixed it in 1.21.4 #226
How it works
- A player crafts a bundle
- Sends specifically crafted packets that would crash Minecraft
- Bundle Crash Fix: Prevents the handling of the packet → the server doesn't even notice anything — no crash 🎉
