26.1 unknown packet error.

[ZekeZDev]

Apologies there is not a whole lot to go off with this error. If there is a way I could provide a more helpful log please let me know:

lost connection: Internal Exception: io.netty.handler.codec.DecoderException: Received unknown packet id 30

This occasionally happens when switching on the latest version with 26.1 causing the player to get disconnected.
I am not certain this is just switchy's fault as the server this was tested on is behind velocity and uses fabricproxylite.
