Strange behavior may occur and Received state update for view id' SceneID: 2 Level Prefix: 0' but the NetworkView doesn't exist now I have this script dataHandler and car selector in which dontdestoryonawake function is call so that on switching to another screen the selected car can be shown now this all i done by using RPC now i have created two functions in car selection script which has boolen variable and then that function is called those boolen values get true and as dontdestroyonawake is applied so those values are called on car controller script and other things are done now the problem is on loading a level through client side those error pop up and these values are not called on car controller script dataHandler script and car selection script is on gameobject name dataHandler on screen name carSelector and car controller script is attached to every car and data implemented in attached on gameobject data implementer in screen car controller need urgent help
