Need Map Help, Messed Something Up

Hi, I am running Mad Mage, D&D 5E. We just transitioned our game to Roll20 until this Corona virus stuff is over. Anyway, I did a thing that messed up a portion of my map and could use some advice as to how to fix my mistake. Here is a screenshot. I bought the module so it is supposed to have the dungeon there, but it is just the fog of war with what they have uncovered so far. Any advice as to what I messed up and how to fix it would be much appreciated.

It's possible you somehow deleted the map. You can either create a new game and vault your characters into it, or try writing to <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a> and see if they can't fix it for you. There's also a workaround, where you create a new game based on the module, assign the missing map to be a character's token and then use the Character Vault to move the character and graphic into your original game.

Ahh, okay. I figured it was something like that. It is easy enough for me to use my screenshot and migrate everyone to a new instance of the game since it was our first session using Roll20. Thanks!
