I am working on a project and at first I was using the brush tool without using auto flatten. Then I started using auto-flatten and now when I make a stroke Harmony freezes. Can someone help me? Could it be that I made so many strokes already that Harmony cannot handle the new strokes or is it something else?
You should contact support to have a look, it can be due to many
different factors. What happens when you save and re-open the scene?
Have you tried flattening the image in the layer to merge all the strokes
into one?
