Is the Collider component on the flies mark as a trigger, there should be checkbox called IsTrigger.

I also have the same issue, The Fly Is Trigger is checked, but the tag is selected to untagged. And the player is selected to player tag but Is Trigger is unchecked. I believe thats how it has to be but still doesn't work. The error says..

UnityException: Tag: player is not defined. FlyPickup.OnTriggerEnter (UnityEngine.Collider other) (at Assets/Scripts/FlyPickup.cs:12)

I'm having the same problem - I get MissingReferenceException: The object of type "Object" has been destroyed but you are still trying to access it. Did I miss something somewhere, I have watched the videos a couple times now.
