Prefab inner reference breaking down...

I just spent a whole day tracking down an issue that on a context reload - such as when pressing "Play" - prefabs would lose all their references. The example I was working on was simply a Canvas with a Scrollbar in it.

If I do this;

Code (CSharp):

1.     [InitializeOnLoad]
2.     public class ViewCreator
3.     {
4.         static ViewCreator()
5.         {
6.             EditorApplication.SaveAssets();
7.         }
8.     }

There's a high chance that any already-loaded prefab - like being inspected - will lose all their references.

In short, SavingAssets on a InitializeOnLoad is a recipe for disaster, which is annoying since I'm auto-generating assets on a reload of code.

 

Did you report this as a bug ?

 

Not yet... I should.

BTW, reproduced on 4.6.1, 4.6.5 and 4.6.6.
