NPC Spawn Issue: Wandering Festering Hag (Unrest)

[BarackObooma]

I was moving my 35 Cleric to Unrest to try the festering hag room. I was surprised to be met outside the door of the hag room by a fourth festering hag! I checked in the room and the 3 spawns were also up.

Was this recently added or is it a bug? I can swear there was never another hag outside the hag room.

This one wanders in between the hag room and the bar. It wasn't from a train elsewhere or anything. I watched it for several minutes as it pathed back and forth (with IVU of course).
