UITween bug after update to 3.0.8

[Sobraj]

I have a UISprite which has an initial alpha value of 0. And on that sprite I have a Alpha Tween from 0 to 1. After I updated to 3.0.8 it stopped working. If I manually set the alpha while running it works. But if i play the tween in reverse so that the alpha becomes 0 again, and then play the tween forward again it does not work anymore.

Calling MarkAsChanged, MarkParentAsChanged or Refresh (on the panel) does not work either. Is this a bug from the performance update? Or do I have to do something extra?

You'll need to provide more details to go on. A quick test:

1. New scene.
2. ALT+SHIFT+S to add a sprite.
3. Set alpha to 0.
4. Add TweenAlpha with "to" of 1.
5. Hit Play

...reveals nothing wrong. Sprite fades in just fine.

The tween script is disabled at start and only gets enabled through code. The object is a prefab and is added to a UIGrid through code. And when clicked on the sprite it is faded in.

Did not test it yet in a fresh scene (have had no time yet). Will test it in a new scene once I got the time.
