Headless spawned too late

This is definitely a rare occurrence, but not a bug. Demon is a little open-ended when it comes to spawning: the chance is VERY low, but it is within expected behavior for a unique to occasionally show up very late... or, very early, for that matter.

Huh didn't know that. First time seeing unique demon so out of place.

Yeah, uniques tend to be "stickier" than most demons, because they have a higher chance to be picked to spawn than most demon groups on a floor's table, and of course, once they spawn once, they never can again. But if they happen to get missed, it's theoretically possible for them to spawn on any higher floor, though after +2 the odds become rather remote.
