What the heck is this?
“The referenced script on this Behaviour is missing!”
It says:
"Assert in file: C:/BuildAgent/work/812c4f5049264fad/Runtime/Mono/MonoBehaviour.cpp at line: 1514
You had a script attached to an object, then deleted the script without removing it from the object.
–Eric
If you click on the error in the console it sometimes highlights the object that has the deleted script attached.
But I checked all my scripts on all my gameobjects… they all exist 
re attach it and be done with it O.o
check your prefabs that not exist on your scene
I get this too, generally the message is correct, it reports incorrectly linked objects. However, in one of my test projects it reports this, but the project still runs.
I think it’s a bug in Unity.
Hi pivotraze - i too have this exact error
did you find a resolution?
Do not forget hit “apply” button in inspector upper right corner where it needs! Just fixed the same problem.
