Prey Bugged?

I completed 2x nightmare prey fine (ZulAman and Eversong) but ive just killed my target in Harandar and Voidstorm and neither allows me to complete the quest?

Both times it just say "Complete" but can't get the rewards or trigger the completion for the weekly.

I've tried /reload, a full relog, going to astalor's sanctum then back prey location but nothing is working.

The only thing I can think is after the first two I activated war mode. Does that block prey completion?

Anyone else?
