The NPC Patient Vaargo seems to be bugged still. The Great Shellkhan is there, not dead, Patient Vaargo is not afraid and standing around fishing, I get the “The Great Shellkhan” announcement when I come into range, I have the box of fish, everything is right. The only weird thing I can find is that when I click on Patient Vaargo and they talk, half of the time it’s an old lady Tuskaar voice and half the time it’s a kid Tuskaar voice. Maybe it doesn’t know what NPC is there some of the time?
**edit; it’s also overlapped with the Great Hunt at the moment, also a potential issue.
