Another disconnect and map and all loot disappeared

This is the 5th time in the past few days that this has happened. Right now my latest disconnect happened when I was playing and someone sent me a whisper and I immediately disconnected - I doubt that is a coincidence.

Anyway, I was almost completely through a map, the first one in my playing session tonight. I can understand disconnects - I have been playing for 13 years so I know the drill. But having a rollback, especially a map I had been playing for probably 5 minutes is nuts.

Just so I am clear, all the portals are gone, all my loot is gone and the map is no longer in my inventory thus it is a rollback from the second I entered the map.
