Hey, can you tell me what is happening on your client to trigger this.
The line numbers don't correspond to what I have here, so I can't really pinpoint what's happening.
I do believe however that this is an issue of the chat packet.
I'm trying to print out packets between the server and client to fix a bug(players cannot move after spawn) of my server. (Would you like to help me with this?) Indeed, after removing the chat packet, it works. Hasn't it been supported?
PS: I have fixed my bug
