In my unity script I load and unload scenes that have AreaTargets (I am using LoadSceneMode.Additive).
Everything works fine while testing on unity editor, but once I run the application on my Ipad I get this error while switching between scenes:
"There may be only one VuforiaBehaviour instance in the scene"
sometimes, I get another error:
NullReferenceException: Object reference not set to an instance of an object"\.
DefaultObserverEventHandler.OnDestroy () (at <0000...000>:0)
Does anyone have any idea about it?
