The Animator

Not sure how to explain it since it's pretty random but when I'm using the editor, on canvas size or brush, sometimes if I try to use the undo button it removes multiple separate lines, not just the previous one, and even using the redo button doesn't get it back it just reads it as the same line.

Me too

yeah same, usually on my pixel art

its like if you do a couple lines quickly then undo it gets rid of more than one of the lines
