While I was conducting class a few days back, I did a demonstration on the Tween class and discovered a bug along the way.
The bug can be easily reproduced by using a Timer and creating a large number of Tweens on a large number of objects on the screen. What happens is that some of the tweens will proceed halfway and then hang there indefinitely. While others might continue tweening. The occurrence of the bug is completely random. If you have answer to this quirk/bug, please leave a comment below to let me know.
