What I meant is the hitcircleoverlay animation string. Having no hitcircleoverlay.png along with the animated string would replicate that screenshot, except that the individual hitcircle would be animated but the slider hitcircles won't (in this case, slider hitcirlces will use the first frame and let the next frame pop milliseconds after the hitcircle was clicked, iirc). I barely have small memories about that; I hope I could replicate that again. For the hitbursts animation, they are very fast that you would need around 60-90 frames to get it right. The consequence will be a heavy skin size = w=b
