I was busy tweaking a duplicated brush when Affinity Photo 1.9 froze. I shut it down, reopened the program: all of my imported brushes were gone. Turning the ipad (pro, 2020) off and on did not help.
I just found something else that is strange. Again I am adjusting a brush. While testing it with strokes, it actually put down what seems the original textures that are used in the brush. I have never seen this happen before. I had already removed the second one (and could not get it back, so there really is a problem, because usually I can go back 5,000 steps or so). I am adding a print screen of this.
