I installed the open-beta today to claim the reference cube and the various other bundles which are currently avaliable to test out some stuff for the first time. I notcied however that some stickers and the cube item have duplicated in my inventory. I tried restarting VRChat to see if it was just a visual bug but this didn't fix anything.

Furthermore the duplicated items and stickers also show on the website.

I claimed the bundles on desktop mode, though unsure if that means anything.

EDIT:

I added more screenshots showing that even though I have two cubes in my inventory, I can only place down one as after I do both options appear to just remove the cube. The same applies to my duplicated stickers, I cannot place down 2 of the same sticker.
