Mythic gone after disconnect crash

I had mythic drop in zir latter boss. I dropped an item, from my currently full inventory, on the floor. Piked up the mythic and posted in party chat to let party know " yey i got a purple". I was disconnected. Waited to reconnect because “character was not finished saveing, try again later”. Logged in and did not have the mythic item. Save state was after unique item was dropped because i had a single free inventory spot open. Did not save the mythic item pick up and post into party chat save, but party did acknowledge i posted it in party chat. It was in my hands and posted as proof i was lucky to get it. It did not save tho. Is there a way i can get it. I had it and did not choose to disconnect?
