Hello.
I was painting today on something I've been drawing for a long time... and I did not save it. All of the sudden, I hit "Undo All" by accident while my screen freezes... then, I was clicking around and I apparently moved the pixels and now I am stuck. I can't redo my history, and I don't want to have to redo the WHOLE THING. I realize how important saving is...
Is it possible to restore it?
