Sorry everyone, I should have mentioned this on Friday, but I was in a rush and technically working off-hours when I found and fixed the problem.
Our server suffered an attack on Thursday night, and we lost our Rival Ball database. Some of you noticed your accounts were missing, and this is why.
Luckily, our new backup system is working flawlessly, so when I discovered the problem on Friday I was able to restore to the version of the database from Friday morning.
Sorry for the inconvenience. Let me know if the database restore has caused any persisting problems.
