[Shimmering Expanse] / [Vashj'ir] Captain Vilethorn/General Nazgrim questline script not working

[Distorted]

I have completed the quest https://www.wowhead.com/quest=25963/swift-action and at the 40/54 coordinates where both of the NPC's were supposed to be, before turning in the quest. Later on they would move toward the 39/78.6 coordinates in the zone. 

This is the only thing I see in this zone and the phasing is not properly scripted. If I move they simply phase out and I am stuck at 105/130 with the quests unable to get the achievement.

 

This is how the script was supposed to go like. The captain and the general were still at 40/54 when I turned in the quest, but they simply vanished. 

Please do script this! ty!
