Ne1 heard of this?

I was in a game trading an ohm rune and a HoZ shield for a whole bunch of stuff. there were 3 people in the game and i was in the trade screen with 1. I suddenly get a connection interuption, which isnt that far out of the ordinary for me. i get a realm down and restart my internet. when i get back on that char to kill baal in hell to lvl i find that both my ohm rune and my HoZ have mysteriously dissapeared. What happened and why?
