Images back to October 7th appear to be gone.
Image edits were rejected for the past day or so due to the new images being missing. So if you got an image edit rejection, this is why.
EDIT: I fixed what I could. I only still had maybe half of the images I had made or updated entries with in the affected time period. But the Genesis/Mega Drive hardware section is fixed.
NOTE: that the statement of "images were lost" is not the only thing. Image edits were reverted on entries, but it is not reflected in the history. For example, on this Laseractive pack:
https://vgcollect.com/item/14538The entry had the pack as the front art. I renamed the entry on 10-16, put the box art on front art, and the pack on cart art. On 10-23 (this morning) the history was still the same, but the front art was the pack again (as it was on 10-16) and the cart-art was a broken image. Now I re-put the box and cart art back, and see how the history tab appears.
