I keep encountering this problem:
I am copying a large number of components from one project to another. After I paste the components in, I need to move them to the right location. Everything looks good, I finish my edits and go back to the Prototype. Now it looks like I have two sets of components, one in the original pasted location and another in the new location. When I go back to Edit, there's only one set in the new location, until I hit refresh (it doesn't matter how often I go back-and-forth between prototype and editor, I have to hit refresh to see the original set).
I have to then delete the original components, which is quite a pain as they're often mixed up with the new ones.
