I noticed this about 2 days ago, but my stuff vanish when I'm trying to customize my avatar. I have never traded on my account and it hasn't been hacked because half of my hairs, face accessories, and classic clothes are just gone. Not all of it is gone just most of it btw. Some of the outfits I have saved still have these missing items and they appear only when I'm wearing the outfit.

When I look at these items on the marketplace it says I own them, but when I click to go customize it, it's just not there. Again, I haven't been hacked because if I did then my headless head would be gone. Is this some sort of bug? It happens regardless if I'm on pc or mobile though I did notice it started when I was on mobile.
