I’ve updated to v3.4, and now when opening the UFOs in Glyphs the production names are converted to the Glyphs names (e.g. `uni0431` to `be-cy`) despite the tickbox “Keep glyph names from imported files” in preferences being checked.
The glyphs order is also jumbled: in Font View there are multiple “Letter, Cyrillic” sections with 1, 2 or 3 random glyphs spread over several lines.
In the few files I’ve tested this happens to Cyrillic, Vietnamese and some symbols and arrows.
