Unable to edit main components I noticed this issue last week, when I tried to edit a main component (icon button in the screenshot). I knew it was a main component (I had created it couple weeks ago and then it worked just fine), but as I tried editing it, it was shown as an instance. I brought the main component from the assets panel (right click -> Edit main component) and it gave me just empty brackets indicating the icon button. There is no way to "turn up the opacity" or anything like that. When I go to Layers panel, I have all the layers there, but as I click through the elements, they are all invisible. The prototype I am working on is going to production, and right now I have no way of updating the prototype, unless I do all the edits in every artboard manually. This also happened to majority of the main components in the file. Some were intact, but only a few. Version I'm using: 48.0.12, Windows 10 Pro.
