Nostalrius Begins - Quality wow vanilla realm (1.12)

Today in AV the alliance killed Korrak at the 2 hour mark, it was AV 3 around 3:15 server time and none of us received credit for it. I was wondering if there was a way to change this or look into it. I've been trying to get this quest done forever and once I finally thought I did, it bugged. Just frustrating.
