Mark glyph anchor duplication

I’m seeing anchor points being duplicated when I open a UFO. For example, my typical diacritic has two anchors:

    <contour>
      <point x="273" y="1316" type="move" name="_diaA"/>
    </contour>
    <contour>
      <point x="265" y="1746" type="move" name="diaA"/>
    </contour>

but after Export to UFO there are three:

    <contour>
      <point x="273" y="1316" type="move" name="_diaA"/>
    </contour>
    <contour>
      <point x="265" y="1746" type="move" name="diaA"/>
    </contour>
    <contour>
      <point x="273" y="1316" type="move" name="anchor"/>
    </contour>

I can see the extra anchor when viewing the glyph, so the duplication happened when opening the UFO.

I don’t remember this problem before, so might be a recent regression. I’m using Version 2.4.2 (1038)

Just wondering if I’m the only one who is seeing this, or maybe there is something I’m doing wrong?

Sorry for not replying earlier. Could you send me a sample .ufo file?

Thanks for the file. The extra anchors are imported from the feature code. I’ll try to optimise this.

This remains an issue with build 1060. Any prospect for a fix?

That is also addressed in the next version. I will not add functional changes to version 2.4.

Appears to be fixed in 2.5b (1066). Thanks!
