Hey there @Kiwi-Hawk! Welcome back to the community! If the assets themselves haven’t been fully removed and just made private, this sounds like it could possibly be a bug on Fab’s backend, so we’ll definitely have to make a report to the Fab team. To do so, head over to this side of the forum and select the “New Issue” button on the right. This will make a new post with the template needed and the correct tags for the Fab bug triage team to take a look at.
