Regardless, this is where Protobuf comes in.⤶ ⤶ # Why Do I Care⤶ ⤶ Some hooks may pass a Protobuf class and it is important to take note of this. ⤶ ⤶ Changing the Protobuf class will LIKELY NOT change the entity, however it can change what data will be sent or received. It's an important distinction because it's effect may not be instantly seen.
