Nyx was fiddling with it earlier to try to get it to stop showing the old Valkyrie Helm sprite in place of certain headgear sprites. I'll let her know.
Follow-up: Nyx updated the CP sprites, so everything should work right now. I hope that helps! If you run into any further errors, try to narrow it down to a specific headgear so Nyx can check its sprite. Thanks for the heads up on this one.
