Heya I was wondering if this is a bug in Framer Studio:
Flipped states with masked elements are behaving weird:
uploaded a zip with sketch file and framer files here: http://filevoid.net/Eira_barbatabcw
when sketch flips a shape it keeps the original coordinates of the points and applies a transformation, instead of actually changing the coordinates. unfortunately SVG renderers often ignore the transform. try hitting the "flatten" button in sketch? i'm not sure if that will remove the transform or not
Convert the shape to outlines in sketch!
Flips on the last group or any object works. But flips on parent groups are ignored. Hopefully something we can fix, but perhaps with this info you can work around the problem for now.
