I am not exactly sure what happened, but a character died and while I was taking his stuff out of the dropped bag, one item disappeared alltogether before I could grab it. The item was a mace, and since my keyboard started to act weird soon after and I had to log off, I never learned to know if it was a mundane mace or magical one. Anyhow, it disappeared. I think I managed to get all the other stuff from the bag. When I left the bag, it disappeared also, so assumingly it was empty.
I know there was a DM present at the situation, I don't know if he noticed this.
