I have a strange bug. I have a game object with a TweenPosition on it. When the tween finishes I want it to call a function so I create the function and add it to the OnFinished Notify method. The object has a collider on it and I use UIButtonMessage to call a function when I press the object. That function activates the tween on the object. The teen happens about 50% of the time but occasionally I get an exception (null pointer in UITweener) when I look at the onFinished component on the tweenposition the method has gone! its just an empty box.
I use this method on many other buttons with no problem, but just this one goes wrong. any ideas?
