Forum post: https://scratch.mit.edu/discuss/topic/613102/ Large projects with many costumes have always had trouble loading in Scratch. But until recently, you'd get a message saying the project couldn't load (presumably due to a timeout), and you were given the option to try again (reload). Reloading often worked. Recently, some change in Scratch has caused these projects (e.g. my own Powerpuff Yourself project) to load on the first try, which seems great. The problem is, that some costumes seem to not be loaded. Instead, a placeholder is shown (question mark image, see sample screenshot from my project Powerpuff Yourself). I propose that this is a bug, and any change to Scratch which causes it, should be reverted.
