Sorry about that, the game wasn't working from about 12:05am ET today until a few minutes ago. The server ran out of disk space and this caused all sorts of things to go wonky.
Embarrassingly, this has happened before (and again, even). I periodically compress old database backups and log files to avoid this, and even less periodically transfer them off the server, but if I ever forget to do this for awhile, as was the case here, this happens.
Anyway, I'll be looking into ways of avoiding this in the future. Log files should probably be kept on a separate partition or something so that in the event that it does fill up, it won't affect everything else. Sorry again!
