[Ryu-Kazuki]

I had something similar happen to me, I don't know entirely how, but all my items unequipped themselves, and my weapon somehow managed to clone itself during this process.

I didn't battle, I wasn't in PvP. I was just standing outside the mage guild and the game rebooted.

My character does have a rather large inventory, and I think that might be related to it, but I'm not 100% sure.

Loading savefile...
Now loading character inventory. Total Size: 227. Please be patient!
25% done...
50% done...
75% done...

I managed to re-equip everything, but the screenshot still shows the cloned weapon.
