Strange behavior when editing paths

I’m trying to create custom SF Symbols, but when editing a path and clicking “Finish Editing” Sketch sometimes does an invisible extra editing step which breaks the interpolability of the symbol in the SF Symbols app. Only when ending the editing mode of a path, another invisible editing step happens. I can undo this second step, and the symbol is fine. But since I need to make a lot of edits, I can’t check every time if this mysterious step happened.
Update: I looks like sometimes a path just gets cursed and the next edit will break it, even without an invisible step.

Hi @Leo

I’m intrigued by this situation and would like to help you get to the bottom of it. Could you please share a screen recording of all the steps you take to experience this issue?

If you prefer to keep it private, feel free to send that information to productsupport@sketch.com.

Cheers :pray:
