Hi, the version 3.7.2 not solve the problem... this is the situation :
1. New scene.
2. Two sprites, one with a TweenColor on it that makes the sprite red. Another sprite has a UIPlayTween on it and a collider.
3. The UIPlayTween references the object with the TweenColor on it.
4. TweenColor is turned ON and GameObject is enabled and visible
5. UIPlayTween is set to play OnClick, Play Direction REVERSE, If target is disabled ENABLE THEN PLAY, If already playing RESTART IF NOT PLAYING and When finished DISABLE AFTER REVERSE.
Now I hit Play, the color of sprite changes automatically to red, click on the sprite with the UIPlayTween but the
the red sprite is disabled before tween reverse you can see that the red sprite is disabled before the tween reverse start and before it is completed
