hello, I'm getting the the same problem, but mine is:
Inernal exception: io.netty.handler.codec.DecoderException: java.io.IOException: Packet 0/26 (pn) larger than I expected, found 184 bytes extra whilst reading packet 26
I use TLuncher
If you need the server, can I send it in private? I dont want to disclose my friends server to public. (if so, tell me how)
