Map Images missing

While I was re-organizing my maps into your wonderful folders (seriously I love them), I noticed that some of my map images have completely disappeared! Everything else is still there, dynamic lighting, tokens, etc. but everything on the map layer is just gone!

Everything else is still there, dynamic lighting, tokens, etc. but everything on the map layer is just gone! Did you - by accident - delete the Map from your recent Uploads? If the Image for the Map is not there, then it cannot be displayed on your maps.

While I have accidentally done that in the past, this time I did not! These were images added after said incident, and I haven't deleted anything since then, so as to not have that happen again.
