Issue description
My friend asked me to help solve an issue of player randomly get disconnected from his LAN world and get a message "Illegal packet received, aborting connection".
After finding out that the message was in NetworkHooks.validatePacketDirection(), I did a mixin there and found out that the expectedDirection seems to be wrong (PLAY_TO_SERVER but it's received on client). But at the point of the mixin the packet hasn't been decoded yet so idk what it actually is, but a line of log:
[minecraft/ClientPacketListener]: Unknown custom packet identifier: utilitix:netchannel
gets printed out after each time the mixin is triggered, I don't have much time to figure out what the problem actually is right now, so I thought I'd just report these findings here.
Steps to reproduce
The problem seems to be very random and hard to reproduce...
