Hello, recently I have been working on creating a custom modpack with about 200 mods.  I got it working today and was able to create a server for it.  Upon joining the server, I get kicked with the message: "Internal Exception: io.netty.handler.codec.DecoderException:  java.io.IOException:  Packet was larger than I expected, found 71 bytes extra whilst reading packet 28" I have spent over four hours trying to fix this error but to no avail.  I suspect that it has something to do with forge. Any ideas?

Forge Version: Forge-10.13.4.1614 (To my knowledge)
Java Version: Java 8u51

Minecraft 1.7.10 is no longer supported here. You should update. There are plenty of great mods for the new versions, and if you really want one that's only on 1.7.10, tell the mod author to update.
