Game Disconnecting Due To Packet Overflow?

I'm trying to connect back into my game but I keep receiving this error message:

Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Packet 0/36 (ki) was larger than I expected, found 3 bytes extra whilst reading packet 36

No idea what this means, but this occurs when I'm in a sewer section near the beginning of the game. Can't check what quest because choosing my character loads for a second and crashes. Any help would be appreciated.

 

1.13 causes this, try playing in 1.12.x , that's the most stable version right now.

 

Don't use 1.13, use 1.12.2.
