So I have this weird problem where sometimes I'm advancing a frame at a time and then after a second it changes to a different frame. I thought it was a weird quirk and worked around it. But then one of the videos in the center previewed strangely with certain frames stuttering back and forth in the middle. I thought maybe it was just a preview issue, but then I had exactly the same issue when I rendered it to a final video.
Aw man... You think I would have thought about doing updates first... I'll do that now and see what happens. Thanks!
