So Nether Disruptor came up, logged over to my DH on Ner'zhul to get the commendation, got it, logged over to my Druid on Sargeras, got it, logged off for the night. Woke up started doing the quest chain on my druid, completed and crafted, put it up on the AH. Logged over to my DH, item is gone, quest is gone, submit ticket, told i was shit out of luck because blizzard employees are shit.
