Actually she's setup to be a 78 second respawn just like a few other named cycles like Grizzle. Most wandering trash are 36 seconds, while aviaks are 2-3 minutes. So, when you do find a 78 second repop and track it, you're on a named cycle.
However, that's clearly not the case as that's what I've been doing. I've since tried breaking Angelox's script
here. I figured that since only 2 calves and a lioness path through paw besides a werewolf and Brother Qwinn, I may have something. Several hours later and no Quillmane spawns, I've given up.
Maybe I'll try spawning her again when someone actually sees her on this server.
