Has anyone else noticed that the last version of Craft completely messes with nested symbols in Sketch? Previously, Craft allowed you to maintain default overrides for your symbols. If I had one symbol for a green button and a blue button was simply the green button symbol with a background override, Craft used to maintain both of those as separate buttons. Now, Craft doesn't respect the symbol overrides and syncing with Craft will force the blue button to become the default green button.
Craft is pretty amazing, but I'm getting concerned about building out our entire design library using it. With these kinds of changes, I can't risk our entire design system getting wrecked.
