Call the OnTermination(ActionFSMBaseStopEventTState, TData) hook if you want to retain this behavior. When overriding make sure to call base.PostStop(); Please note that this method is called by default from PreRestart(Exception, Object) so override that one if OnTermination(ActionFSMBaseStopEventTState, TData) shall not be called during restart.
