missing loot and boss

[jewpacabra]

Hello, our guild (invictus - at Outland realm) fight in the hyjal,and killed the 4th boss, there was a disconnect of the server during the distribution of loot. we have stream and screenshoot where loot is seen.
After the server turned up boss was dead and all loot is gone, items were lost even in those players who received loot before disconnect. and we cant start encouter again because boss is dead. It was not our fail so can we get our loot back, or reset boss?
That are very necessary for our guild for further progress.
Players who recive/should got loot:
1) Jevvpache - Gloves of the Forgotten Conqueror
2) Magicway - Gloves of the Forgotten Vanquisher
3) Yomayo - Bow-Stitched Leggings
