Guard Lesunra in Paineel

[Nachtsuchen]

Guard Lesunra in Paineel, a skeleton, attempts to flee from combat after their HP reaches a certain minimum threshold; the other three similar skeletons in the area of similar level approximate to Lesunra do not attempt to flee. I understand some undead do attempt to flee but that it typically is not the case, and this one of the other three seems inconsistent to their behavior and seems erroneous.
