One of my friends told me about this bug over Skype, so I summarized what he was saying below:
Essentially I noticed that viewing my uploaded decals from the Develop tab shows decals as awaiting moderation, even though when clicked on, they have already been accepted. I uploaded a bunch of decals a couple days ago, and upon checking them this morning, only one appeared to have been accepted in the develop tab. Upon further inspection, all of the decals that appeared to be awaiting moderation to me had already been accepted and could be viewed in their individual item pages. These assets will also appear in game as if they had been approved.
Edit 9/24:
Something similar is happening in my inventory as well. I uploaded a bunch of shirts the other day, and although they are all visible when I wear them or whatever, they still show up as pending in my inventory
