So I was working on PtB and then my Scratch crashed. When I reopened the project, there was only one sprite left. It was this. The backgrounds were all gone too except one, which was just a black screen. I tried to delete the sprite and the background, but they wouldn't go away. I tried to make new sprites, but I also couldn't do that. I couldn't give them any names either, so that was weird. I tried to type in a title, but it wouldn't let me. I was still able to type in instructions and notes and credits, so at least I can tell you guys about this. If you guys have encountered any similar happenings, let me know in the comments.
