JavaIO exception.

**Describe the bug**
Sometimes when switching lobbies or joining a game 5zig packets cause a JavaIO exception and I get kicked from the server.

**Expected behavior**
Game should not produce a JavaIO Exception..

**Desktop (please complete the following information):**
- OS: Windows 10
- Version 21H1 build 19043.1288

**Additional context**
Log file
[fml-client-latest.log](https://github.com/5zig-reborn/The-5zig-Mod/files/7392462/fml-client-latest.log)

The issue involves network packet handling in a Minecraft mod. Start by examining the log file linked in the issue to identify the specific JavaIO exception stack trace. Look for packet-related code in the mod's networking subsystem, likely under a package like `net.the5zig.mod.network`. Reproduce the issue by switching lobbies or joining games while monitoring network traffic. 'Done' means the exception no longer occurs during these transitions.
