It's a new bug. I've had wordmarks being uploaded but refusing to update on the wiki (after days of waiting). The same is happening with images. For example, I uploaded 2 days ago, noticed I missed some shadow on the bottom right hand edge that I removed and re-uploaded. And it's still showing the old image in the table, in the file shown on the page, in the file itself (when you click on the file) and every page it's used on. It used to take a couple of hours at most, days is definitely a bug.
