        # Disconnect Packet Fix for Fabric and NeoForge

A mod for Fabric and NeoForge-based Minecraft servers that works around the [MC-271325](https://bugs.mojang.com/browse/MC-271325) bug. This bug frequently causes the console to be spammed with exception stacktraces, e.g.:

```

This mod serves to fix that until Mojang fixes this bug. The mod itself is extremely minimal, only using a single mixin to inject code to one method.
