About this Mod

This mod safely modifies the core read method of Minecraft network packets.
Whenever any mod attempts to write null into a packet, the method automatically replaces null with an empty CompoundTag at the return stage, ensuring that any subsequent NBT operations (such as getString, getInt, etc.) will not throw a null pointer exception.
