Possible bug in the ladder

Recently, I checked my ladder rank and, to my surprise, I'm now in 54th place. I was first in my league, and now I find myself at the very bottom. How did this happen if I haven't changed anything, and I hasn't lost any matches recently? Is this something new, or just a simple bug?

Could anyone tell me what happened?? Thanks in advance.

Oli.
