"The Warpack" quest bug

The warpack quest drops me off at temple of the prophet, yet it doesnt say that I have ridden with the pack(even though I did) and also I cant find the King to turn in the quest. Im pretty sure its a bug. I have tried reloading, restarting, abandoning, pretty much everything. Problem is, I cant advance in the storyline because Im stuck at this point. I have seen a few people have the same issue online, yet no one knows how to fix it.
