Nostalrius Begins - Quality wow vanilla realm (1.12)

Hey guys

I am escorting Taelen Fordring through Hearthglen, and he chased a mob into a Guard tower, killed it, and is now just standing in the Guard Tower doing nothing. Taelen has been here for over an hour, killing the mobs that respawn. I can even restart the quest. Is there any fix to this?

Thanks

If you find out let me know, same boat.

Ask GM to reset it in ticket.
