Emoji.css, emoji.png, standard-icons.png not downloading

I’m sorry, I can’t remember exactly and I’d prefer not to cause the problem again right now. I do remember that the information screen was listing that at 0%, and requiredFiles.xml was showing it as still in progress, not complete. But then again that’s true of standard-icons.png, emoji.png, and emoji.css, and I don’t even know why those would be in a list of required files; I don’t remember using them in my layouts.
