I run a number of compaigns on roll 20 and recently all of the content from my art folders disappeared after I reorganised my folders. I can still see the content I have uploaded but everything put into folders has gone. folder names are still there. My dynamic lighting is still in place on the maps along with the tokens but the maps have all gone. Have tried clearing extensions and the cache and have just tried Firefox, (normally use chrome) but same issue. I have been able to reupload some maps so I can continue to play but very frustrating. This has happened across every campaign I am running
