I have a saved copy so it’s not that bad I didn’t lose much. However I would like to know why this happened so other people who don’t make frequent backups don’t get into worse situations and incase I forget to make a backup.

@Luke @danger_kitty if this ever happens to you again, if you could immediately open the developer tools and copy everything in the console then I would extremely appreciative!

To open the developer tools it’s `ctrl-shift-i` on windows and `command-option-i` on macos

Okay yeah when it happens I just load up a backup and continue coding if y’all could fix it I would like that but I know fixing bugs is hard specially, if you don’t know what it is

@richard it seems to be something to do with the sprite data extension
