By profile I mean the picture of your knight at the very top left!
So whenever I enter a new zone / level, my knight's accessories just disappear. Sometimes it'll fix itself when I go into a new zone but most of the time I need to wear new equipment for the accessories to come back. It also happens when I pick up a crystal (Luminite, Valestone, etc)! Since picking up the crystal updates your profile, it also makes my accessories disappear.
Any idea how to fix this? It's constant and it's annoying. Full-screen, windowed, I don't think it matters. It just happens constantly even if I don't tab out during loading (I heard tabbing out creates this glitch). I play on Steam if that matters.
This is mostly just a visual glitch where it renders the knight profile up there when the scene changes or the character updates. Sometimes you'll get your portrait up there blinking if you're on high graphics, which can be rather silly.
Nothing wrong with your game, it's just something that happens.
