This CAN happen if a game is really big and has a ton of Maps / Handouts / Tokens in it. It has NOTHING to do with Transmogrifier or Copying Games. Had this once myself!
Andrew is right, Roll20 Team is the only one that can help you here and ONLY a Rollback of your game will help in this case! (That is, if you don't want to sort everything again yourself)

Hi,
I have a game where I upload my draws, sheets and handouts, then copy them to start new campaigns. Recently, 90% of my classified things, hundreds of them, were ejected from the folder and put in alphabetical order at the bottom. IT also randomly ejects them when I copy games. What is going on? I am losing months of work with that...
