Missing Curves

[smth]

I just tried this app out on about 20 SVGs (created in Illustrator), the reduction in file size was significant. After a quick inspection of the resulting files, there appear to be three which have issues. The images below were symmetrical before optimisation, and now, as you can see, they are each missing a curve.

This sounds like an issue with SVGO, rather than the GUI. Might be better off raising the issue there instead (and also providing the SVGs for reproduction). Don't forget to update SVGO to the latest version first.
