I'm having a problem that occurs intermitently. Sometimes a UI2DSprite loads the wrong sprite. This seems to happen randomly, so I'm having difficulty pinning down the problem. I've attached a screenshot that shows my scene running. There are 2 UI2DSprites in the scene. I have one of them selected by the Inspector, which shows that it is displaying the wrong sprite. Any ideas what could be causing the problem?

What changes the sprite, and how does it change it?

That's what I'm trying to figure out. The sprite itself doesn't get changed. The sprite's gameObject moves in & out of the camera view using a .anim file animation. I'll record a quick video and post it shortly.

Okay, I uploaded a video showing the issue to youtube: http://youtu.be/10zXOWwhhIw (http://youtu.be/10zXOWwhhIw).
In this video I start & stop the playback of a Unity scene multiple times. Each time should show the same sprites in the same order, but that's not what happens, as you are about to see.
I have 4 UI2DSprites that animate in & out through .anim files. Each UI2DSprite has a unique 2D Sprite attached to that gameobject. However, when I play back the scene, when 2 of the 2D sprites are shown at the same time, Unity will "randomly" use the same 2D Sprite for both of the sprites. I put "randomly" in quotes because I can't believe it to be truly random, which is why I am posting here for some help.
Cheers

One quick additional note. I'm using NGUI 3.0.6 f7 on Unity 4.3.3f1.
I made a copy of my project and tried upgrading it to NGUI 3.0.9, but it messed up some of my UILabel's & associated code, as well as causing strange color issues when using TweenPosition on a UISprite that has a widget color added to it. It also didn't fix this UI2DSprite issue, so I went back and read through all the changes & fixes made to NGUI since 3.0.6 f7. None of them appeared to offer any solution to my UI2DSprite problem, so I went back to my original project with NGUI 3.0.6 f7.

Quick update:
I didn't figure out what was causing the problem, but I ended up writing some functions to animate the sprites with TweenPosition & TweenAlpha instead of .anim files, and now the sprites are showing up & animating correctly.
I'm still curious as to what was causing the problem, but it's no longer an urgent matter to me. If I end up figuring out the root cause, I will post back here with another update.
