Kitava Fail

I was in the fight. We killed Kitava. I watched the loot drop. I picked up a couple pieces as Kitava fell over. As I was picking up loot, I accidentally clicked on the zone door and zoned down to the Feeding Trough... and I immediately popped back up and never got the Kitava kill credit. But my party-mate did. So, it's saying the quest is not complete.. And I have to kill Kitava all over again. *insert irritated face*
