TFS 1.X+ Inconsistency in runonhealth behavior

[Curb]

TFS 1.4.2

I have two deer scripts, one defined in XML and the other in Revscript, that are identical in terms of settings. However, the deer.xml flees as expected, while deer.lua does not.

deer.lua:

local mType = Game.createMonsterType("Deer")
local monster = {}

monster.description = "a deer"
monster.experience = 0
monster.speed = 196
monster.manaCost = 260

monster.health = 25
monster.maxHealth = monster.health
monster.race = "blood"
monster.corpse = 5970
monster.outfit = {
    lookType = 31
}

monster.targetchange = {
    interval = 4000,
    chance = 20
}

monster.flags = {
    summonable = true,
    attackable = true,
    hostile = false,
    illusionable = true,
    convinceable = true,
    pushable = true,
    canpushitems = false,
    canpushcreatures = false,
    targetdistance = 1,
    staticattack = 90,
    runonhealth = 25,
    canwalkonenergy = false,
    canwalkonfire = false,
    canwalkonpoison = false,
}

monster.attacks = {
    {name = "melee", interval = 2000, min = 0, max = -1}
}

monster.defenses = {
    armor = 2,
    defense = 2
}

monster.loot = {
    {itemName = "meat", countMax = 4, chance = 80000},
    {itemName = "ham", countMax = 2, chance = 50000},
    {itemId = 11214, chance = 1150}  -- antlers
}

mType:register(monster)

deer.xml:

<?xml version="1.0" encoding="UTF-8"?>

Try adding monster.runHealth = monster.health on line 16.

Like a charm. Thank you.
