Experience loss?

[Locke_boy]

I went from level 21 to level 20 today .. lost about 600,000 xp somehow.

.. I have no idea why. No, I didn't encounter Bile's avatar. I was killed a few times in battle mode .. but .. could that truly be it? I will even test it now ..

.. no. I just asked a friend to kill me, and I lost no experience from being killed.

So what's going on?! X_X

If I could be restored that's great, but I can understand if that's not an option ..

.. but I think I should be, I lost this from some sort of bug!
