Alliance Stormhiem starting scenario bugged

When you start the scenario, you are given the quest to "Man the deck gun" But there are no guns, no NPC on board... nothing. Nothing has loaded in correctly.

Tried reloading, relogging, exiting and re-entering, and exiting the scenario and restarting the quest... nothing has fixed it.

Don't pick Stormhiem as your starting point if you are alliance.
