OnDeserialize failed Exception=System.NullReferenceException (see below) object=Player(Clone) component=Rhetorical.Networking.StatCard sceneId=0 length=28. Possible Reasons:
  * Do Rhetorical.Networking.StatCard's OnSerialize and OnDeserialize calls write the same amount of data(28 bytes)?
  * Was there an exception in Rhetorical.Networking.StatCard's OnSerialize/OnDeserialize code?
  * Are the server and client the exact same project?
  * Maybe this OnDeserialize call was meant for another GameObject? The sceneIds can easily get out of sync if the Hierarchy was modified only in the client OR the server. Try rebuilding both.

Exception System.NullReferenceException: Object reference not set to an instance of an object.
