I made a short video to demo the behavior I’m seeing.
I’m designing a font with strokes. When I click on an “extra node” and press ctrl-V to paste a corner node that I copied from elsewhere in the same letterform, it first does the blue circle thing which I normally take to mean that components are overlapping. When I try to paste again on a different “extra node”, the pasted component appears on the wrong corner node.
If this is expected behavior, could you explain what’s happening?
