Map somehow changed to lobby map

The map we battled on yesterday when I ran the game has been changed to the lobby map (which I still have) when I logged in to work on my campaign. The PCs and NPCs are still in the same position relative to each other on the ‘cloned’ map. But that is the only thing left from the other map I spent hours making…
I have no idea how this happened, but it is very frustrating…

Hi @Snowsarn

Would you please use the Bug Report tool from that map to report it? The devs very rarely look at the Forums.
