So it turns out that if someone submitted an item using the " Russian Doll" method with bundles, its going to crash the archive.

In this update, I attempted to force each submission inside of a shulker box before submission (It'll automatically put your submissions a shulker boxes when you click the button) as it compresses the data. Hopefully this'll patch the error!

Upon loading the items back into the game, they will be individually unboxed back to their original form!
