Yeah I saw a thread about this on Twitter once. Artists were saying to always save the brush preset when it glitches out, you might never get that exact mistake again lol.
You know, those software glitches can be pure gold. @taylor957 might doubt it, but I've stumbled on cool effects that way too. When the brush acts up, it shows you what's possible outside the normal settings. Trying to recreate the bug is how you learn the program inside out. Some of my go-to styles came from fixing broken brushes. It's not just a fluke, it's a shortcut to creativity.
