NPC Spawn Issue: froglok hunter

[Dravik]

I think the froglok hunter cycle in TT may be bugged. As I understand it, either the froglok hunter or one of the named is up at all times. I had three trackers including myself on my druid in TT for over an hour. We did not see a hunter or any of the named listed below which I believe to be on the hunter cycle.

Can someone look into this for me?

Thank you.
