Disconnect Packet Fix
by ascpixi
Disconnect Packet Fix works around the MC-271325 bug, which floods a server console with stacktraces when players are disconnected.
What it does
On Fabric and NeoForge servers, the bug produces repeated error messages reading "error sending packet clientbound/minecraft:disconnect". The mod patches the code path responsible with a single mixin that injects into one method, and it stays in place until Mojang resolves the bug in vanilla. Only the server side needs the mod, so players join without installing anything. Files are published for Fabric and NeoForge across 17 release versions, 1.21 – 26.3, under the MIT License, and the project is open source.
Key features
Silences disconnect errors
Stops the repeated exception stacktraces that the MC-271325 bug writes to the server console.
Single injection point
Uses one mixin that injects code into one method, so the change stays small and simple to follow.
Temporary workaround
Intended to be removed once Mojang fixes the underlying bug in vanilla.

What the author says
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.
