This issue affects the following items: Valkyrie Helm, Violet Valkyrie, Redvalk, Blackvalk, Ice Valkyrie, Emerald Valkyrie.
Expected Behavior:
Items should have a complete mesh without any holes or missing faces.
Actual Behavior:
Items have a missing face in the right interior of the helm.
(unrelated but the Valkyrie Helms also have a very messed up UV map. While most of it can be chalked up as adding to the design, some issues, like the texture bleeding on the helm embeddings, are clearly unintentional.)
