100% Nothing - No Code, No Costumes, No Sprites, No Thumbnail, No Project You are able to create a project like this when uploading a large project file to scratch - I used a project with a sprite containing over 2000 costumes. After that the editor will glitch and this happens if you attempt to save the project. The thumbnail is broken. This happens when setting the thumbnail to stage. Technically, there are around six of thumbnails. @Vadik1 also created a similar project: https://scratch.mit.edu/projects/159604371/ However that project comes up with the error 'Could not find project' while mine comes up with 'Cannot read properties of undefined (reading 'comments')' - I think this is because a json file exists but is broken. Thank you so much for 1 view!
