I bought a few premium custom cosmetics and was using them to build for days with no problem. Now all of a sudden in the middle of a session I can no longer drag a custom cosmetic structure skin from the cosmetics tab to my hotbar.

The hotbar pulses cyan like it is waiting for me to pick a spot to drop it into (like I always have in the past) but when I let go of the mouse button nothing happens.

Even more bizarre is if I select my inventory tab after being in the cosmetic tab none of my items appear in the inventory tab. I have to close the inventory completely and reopen it for any items to show.

Any help would be appreciated.
