For some reason my rank got messed up. I was rank 5402 or somewhere close to that in. Today when I got on, my rank was all the way back up to 12801. Is there something wrong with the ranking system?

As you were gone people work for there rank.

I knew about that but I wasnt rank 12801 last night or at any other point.

Somebody worked for your rank. It's not going to stop when you get off. Other people play too..

Rfif: Ranks change frequently. There are alot of people playing and your rank could drop easily. All you can do is fight more and achieve a rank that other people wont get easily ;o.
