As the title says, I'm an idiot. And being an idiot, I decided to mess aroun with the file tools in universe sandbox. Doing so, I decided to open up the data folder in the universe sandbox folder. And, like an idiot, I dragged the appearance XML file into the box and accidentally turned it into a ubox file. And I don't know how to reverse it. Now when I try to open US, it crashes. So, I looked in the logs and, like i predicted saw errors about the appearance XML file, which is now a ubox file. So, I need to know how to either get a new appearance XML, or reverse it possibly. Thanks!
