How to Restore Sunless Citadel Background?

While trying to remove something from the map I accidentally deleted the entire background. I lost the Citadel map from the Sunless Citadel campaign. Is there any way I can get it back?

I'm not sure of the options to a free user.  A pro user could create another game with The Sunless Citadel and then transmorgify that map back into the original game.

I'm a free user, but thanks.

Two ways, if you can't or don't want to start fresh: 1 Create a new Sunless Citadel game. Go to the page that has the map, and switch to the map layer. Press "Z" to get the preview and open in new tab. Download the image from that new tab and upload it to your regular game as you would any other graphic. 2. Select the map as above and assign it as the default token to a dummy character. Use the Character Vault to move that character into your regular game and place it where the map was. You can delete the dummy character afterwards.

Sorry for your trouble, but in the future if this ever happens, don't forget to immediately try Ctrl-Z to Undo. Most of the time it brings deleted/shifted graphics back.
