Kuva Lich with Nova Prime Progenitor has Nova Prime's Headpiece Floating Below Their Legs

[Kald-Wing]

I'm not entirely sure whether this is true for every Lich spawned with Nova Prime but it was the case in this one. When spawned with a Nova Prime, Nova Prime's head appears on the Lich's shoulder as it should but the headpiece that moves Nova Prime's 'ears' appears floating below the Lich and next to her knee. The Nova Prime the Lich was spawned with was entirely default and didn't have any attachments, colors, or ephemeras.

Your lich has a sweet mask!

Maybe she decided to equip Nova Prime's ears "there" because Nova called her a dingle berry?
