@VectorStyler Yes, the issue I was having is it was reverting work and removing all Undo steps before that change after the revert. So I could not get back recent changes. This seemed to trigger really when I was Undo-ing much more frequently, for example, repeatedly laying down lines with the Pencil tool and playing with the Stroke panel to get a certain look. When I do another intensive document, I'll try to capture it in better detail. I have other footage, but I have to dig through it to make clips...
