The maximum payload setting doesn't seem to work

[Death-Clawz]

I installed this mod because when I move or place an item I made with the Create mod it kicks me from the server with this error:

Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Payload may not be larger than 32767 bytes

I installed it onto my server and client and verified it's running on both, but I still get kicked for the same issue. I checked the config files as well as in-game through Cloth Config API and they all have the same default setting of 16777216 bytes so I'm not sure what the issue is.

Here's the latest client & server logs: https://github.com/Death-Clawz/minecraft-mod-logs
