I had no idea it happened. A few weeks ago the server went down and had to be reset. The musing team is normally fairly solid on this sort of thing and will fix it quickly.
Just pop into their discord channel as announcements and updates are there for you. I would never panic about something you have no control over.
No, it's happened before. There's no need to worry. These things happen. I'm sure they make everything they can to work things out.
