Equipment Packet Fix

A simple 1.20.1 forge mod that fixes a weird itemstack encoding issue in ClientboundSetEquipmentPacket causing clients to be kicked.

Description

Equipment Packet Fix (1.20.1 Forge)

Mixes into CompoundTag to do two things:

  1. Avoid a ConcurrentModificationException in CompoundTag#write by converting the tag's key set into an array before iterating
  2. Avoid a EncoderException (caused by NullFointerException) in CompoundTag#writeNamedTag by adding a null safeguard

Config

detectExceptions - (default false) Try and log when exceptions might happen, logging the CompoundTag in question
