Mod Packet Fixer

Packet Fixer for Stable Modded Servers

Packet Fixer is a technical Minecraft mod that increases allowed network packet sizes to prevent errors caused by huge NBT data, complex entities, or heavily modded worlds. By relaxing strict vanilla limits, it helps avoid disconnects, timeouts, and crashes when players join a Minecraft server or load dense areas full of machines and structures.

The mod runs on both client and server, making large modpacks smoother and more reliable, especially when your world grows over time. At BoxToPlay, we recommend it for ambitious survival, RPG, or tech packs that push a servidor Minecraft to its limits.
