[Bug] - Images deleted from the Workshop

I was checking the workshop today and there were some screenshots and thumbnails missing from some of my uploads.

I also tried opening the workshop in Firefox, same problem there. Also I found a comment of another user having the same problem

Were they deleted from the workshop for any reason or just temporarily unavailable?

Could be a database or content server issue.
