    Well, this really sucks. I've been trying out this new SerializeReference feature for some days (I didn't when it was still in Experimental), and have run into tons of problems. But this really is not acceptable.
    How is this not still in .Experimental when simple CopySerialized won't work!? How could you release it?
    If only I had known what to expect from Unity. I should've. I shouldn't even have started.
    I am new in this, but look at what I've tried and suffered, not just Shader Graph, SerializeReference.
    Asset Store offered solutions a hundred times better than Unity could. Is this your strategy now and ever?
