Map content disappeared?

[MartianXi]

Was running an official D&D 5E campaign and was having some issues with a map. I'd loaded some character tokens incorrectly (not from CT) and was going to fix the issue later and closed the map. Now when I reopen that map there isn't any content anymore... the map is blank except for a single red pin marker.

How do I replace the map files to fix the issue?

Downloaded campaign from Steam.

Do I delete the XML file and then update?

Hi Martian, welcome to FG.

You can try right clicking on the map in the images and maps list and select revert changes. If that doesn't work you can try right clicking on the module in thhe module activation screen and revert changes there. Be aware that doing the latter will remove any and all changes you have made which you may not want.
