Apparently even though undead cannot be (successfully) manipulated, even they are affected by the bug.

When you're affected by this bug (especially as a fellow empath with few hunting options) it becomes nearly impossible to hunt in an area, especially if the manipulating individual is the only other person hunting in the area.

Could someone please look into this again?

:*(

It's an old bug related to Empath manipulation. If I understand correctly it can sometimes cause the pathing to flub on a mob you use it on, then the critter just hangs out in the room until it dies. It doesn't occur every time, but you stay in a room long enough they eventually stack up. They still count against the spawn rate in the area so eventually spawn rates dry up for everyone else.

Manipulation isn't supposed to work on undead, but they still interact with the mechanics because it enrages them when you attempt it, so whatever interaction the mechanics have with them the bug apparently still occurs.

And again... in stompers. It's pretty terrible as I have a couple characters in that VERY SLIM hunting range.
