Character Sheets Missing? Deleted? Tried Rollback and Failed

Logged into my campaign where a lot of characters are stored and an entire folder and several (60+) characters sheets are all missing. Tried the rollback today (4/19), tried rolling back to previously in the day and nothing was returned. Tried rolling back to 4/18 and still none of the sheets are back.  Would love to have some assistance and get my save state returned if possible. For any of the Roll20 Team it is my campaign [Emmgroth - Main] with the issues. 

Hi Lily! To get dev attention on this, you will need to file a  Help Center Request . It's mostly community support on the forums. Good luck! I haven't always had the best luck with Rollbacks, so I've gotten into the habit of occasionally making copies of my game manually.
