Satchel of Exotic Mysteries

Quick question for you ladies. My fiancee has been queueing on her tank the past three days when the Call to Arms is up, and the past three runs we've done, she has not received the satchel. Tonight, the Call to Arms was up for both tank and heals, so we, as usual, queued together, and lo and behold, neither of us got our satchels! No one left the group, which was one condition she had been told could cancel it when she ticketed a GM, we finished the dungeon just fine, so...what gives? Do you have to queue solo to get the satchel or something?
