NPC Spawn Issue: No Ghouls in Northern Ro

[Thulghor]

I distinctly remember lots of Ghoul trains to the EC tunnel in Northern Ro back when I played classic. It was annoying and scary. I also remember killing ghouls on my paladin at the undead ruins, yet they don't appear to be part of the spawn rotation at all. When I'd get trained at the tunnel, there were at least three of them. I think I have some old screenshots somewhere.

Also, Allakhazam's shows that they spawned there at one point or another.

I'll dig around and see if I can find something older.
