Players below 1.20.4 can't join #998

Closed LostUmbrella58 closed 2 months ago

LostUmbrella58 commented 2 months ago

Hi, I'm using latest BungeeCord and Packetevents dev build (except those 2 pull requests). And I found there's an issue when players tried to join below 1.20.4 clients. Here's the log: io.netty.handler.codec.EncoderException: PacketEventsEncoder must produce at least one message. at io.netty.handler.codec.MessageToMessageEncoder.write(MessageToMessageEncoder.java:99)
