Opening UFO made in Robofont screws up positions of composites

when i open a UFO that was originally made with Robofont, some composites change their position, e.g. inferiors are no longer below baseline or fractions get all mixed up.

Is this a common problem? Is there a solution other than decomposing in Robofont?


I cannot reproduce this with the latest versions of Robofont and Glyphs. Have you made sure that Glyphs > Preferences > User Settings > Disable Automatic Alignment for Imported Files is on?
