Random dungeon loot lost

Okay so I'm in the Ice crown halls reg from the random dungeon selection. Every single drop was an epic cloth upgrade for my Shammy healer! First of all not being able to roll need... Stupid... get rid of it Blizzard it doesn't make sense. Luckily I had a good party and they were willing to give me the loot through the trade window anyway. Unfortunately after a wipe I lost a pair of boots I was given and the loot just disappeared. Then on the next boss the belt that we all rolled for didn't get put into anybodies inventory. All selected greed (as that's all we could pick) and it didn't go to anyone. It made a set of shoulders disappear on me too until I hearthed back to Dalaran, had to hearth because it wouldn't let me on the ship at the end of the run (I would get kicked from the server instead!)

So I gained a new chest and shoulders but lost a belt and boots from the run... Not impressed. I understand that technical difficulties happen but that is just plain annoying.
