I edited anchor positions and they are showing correctly in edit view but the preview itself displays the old version. In my uploaded image the circumflex is still shifted to the right. Only after I click save it starts displaying correctly. Was that behaviour always like that?
Does this happen when you move an anchor just after opening the file.
And can you try to start without plugins. Hold down the Option + Shift key when you start Glyphs.
Yes, it still happens. But I noticed it happens only to an edited anchor with underscore, the other one updates ok.
So if you edit the anchor in the mark glyph?
Yes.
