Bundle Crash Fix

Protect yourself from nasty cheaters trying to crash the server with Bundles!

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 🎉
