Question regarding missing sprites in 4x platform

[fxfx]

I'm wondering how 2D Toolkit handles missing sprites in additional platform such as 4x.

For example, I have 3 sprites (A, B, C) in a Sprite Collection. Then I add 2x and 4x platforms for those sprites. Everything works perfectly when I have all correct resolution images in 2x and 4x folders.

But what if there is no sprite C in 4x folder? There are only sprite A & B.
When my app use 4x and want to display the sprite C, what will happen?
Will 2D Toolkit display the 2x version of sprite C?

It doesn't handle it elegantly, youll end up with incorrectly sized sprites. Make sure you have all the correct resolution images.
