I had two problems come up this morning after changing my Sketch file that I couldn't seem to find a solution for.
First, I moved the position of artboards around and made a few tweaks to the designs, but nothing that I thought would effect Framer. When I imported the file again, a lot of layers were appended with a number, like "menu1" or "item3". In the original Sketch file, the names are "menu" and "item". This of course broke the prototype. I figured out a workaround but I'm not sure why the layer names changed during import.
The second problem I noticed after importing the Sketch file was that any layer that I had rotated in Sketch, was positioned very incorrectly in Framer. The position was correct in Sketch, and Framer's inspector highlighting showed the layer in the correct position, but it was not rendered in the right position. I had to un-rotate the layers in Sketch to fix the positioning problem, which was different than how I wanted my design, obviously.
Any ideas? The only thing I did before changing or importing the Sketch file was to add a license to Framer Studio, as it had been a trial version before that.
