I have a male Lyric that I decided to make into a maleherm. When I decided to make him Tall Lyric, however, he suddenly started using the lyric_tall_booba.Moira.0 art, instead of the lyric_tall.Moira.0. The text of his post-transformation scene in the Hive doesn't mention anything about breasts, nor does his Appearance description, so it was quite a surprise to see him have quite the sizeable chest in his art.
