A few issues here: 1. I noticed that the close animation that's configured from my game over UI doesn't show in the BB preview. 2. Auto hide feature doesn't work for png sequence when placed on UI nodes, instead it only work for single images. 3. When simulating circle rotation loop, there is a noticeable stutter when the circle completes a revolution and is about to enter the next. It happens no matter how equal I make the intervals between frames and how straight I make the graph
