Killed Diablo in normal mode and picked up most loot including 4 Rare items. Game immediately disconnected (although i stayed connected to other applications such as Mumble). When i returned all loot was gone, including what i had picked up. I did not complete quest by talking to NPC in hopes of redoing quest. Attempted to redo quest and nothing dropped.

Not looking for loot replacement, just reporting as a bug since nothing else seemed to be affected. Also, I have never had disconnect issues with game since release.
Regards.
