All NGUI objects isn't rendering after scene switching

[Markov]

Hello. I randomly run into a bug after switching scenes. And when it occurs - nothing's rendering in bugged UIPanel.
After a little investigation I find out that it's happening because one of the UIPanels receives UIPanel.LateUpdate() after it's been destroyed.

1. MissingReferenceException: The object of type 'UIPanel' has been destroyed but you are still trying to access it.
2. Your script should either check if it is null or you should not destroy the object.
3. UnityEngine.Component.get_transform ()
4. UIRect.get_cachedTransform () (at Assets/NGUI/Scripts/Internal/UIRect.cs:198)
5. UIPanel.UpdateTransformMatrix () (at Assets/NGUI/Scripts/UI/UIPanel.cs:982)
6. UIPanel.UpdateSelf () (at Assets/NGUI/Scripts/UI/UIPanel.cs:1183)
7. UIPanel.LateUpdate () (at Assets/NGUI/Scripts/UI/UIPanel.cs:1144)

Solved!
It happens when UIWidget and UIPanel are on one object.
You should make a warning about it.

You didn't see the giant LogError down in the console?
