Okay... here goes; I'm using macOS 8.6 and I was running coldstone's animation editor. I had an attack animation that was 24 frames on directional 8. Every third frame was set to go back to animation 1 (the default animation). I clicked the button to duplicate the attack animation into a new animation and I got one error message after another saying that it couldn't handle some stacking thing and I never really did get out of the chain of errors until my computer froze.
Just so you all know, try to avoid duplicating animations (entire animations, not frames) in coldstone's animation editor. Froze me up good.
