Brawl Box undo problem

[VigilanteNoir]

So This being my first animation stuff, I need a little help. I was using Brawlbox, and I was making mistakes a lot, so I constantly had to undo. However, when I tried to undo, it gave me some error saying Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: Index.

Does anyonne knows what this means and how to fix it?

Do you have the latest BrawlBox? It's .67b.

Stop using undo. I know that sounds dumb, but as far as I know the undo/redo buttons don't quite function correctly...? I think?

Regardless, here's what I do: once you get to a point where you are satisfied with your animation and would like to restart there should you make a mistake, right click the animation name and hit Export, then save it somewhere you'll remember. Then if you mess up, right click the animation, hit Replace, and select your saved animation.

Old-fashioned, but that's something I picked up. Hope it helps.
