TUNING.KRAMPUS_THRESHOLD_VARIANCE should not be zero

My server just crashed and the log info is here:

scripts/components/kramped.lua :

local function OnForceNaughtiness(src, data)
    if data.player ~= nil then
        local playerdata = _activeplayers[data.player]
        if playerdata ~= nil then
            --Reset existing naughtiness
            playerdata.threshold = TUNING.KRAMPUS_THRESHOLD + math.random(TUNING.KRAMPUS_THRESHOLD_VARIANCE) -- !!! LINE 144
            playerdata.actions = 0
        end

        for i = 1, data.numspawns or 0 do
            local kramp = MakeAKrampusForPlayer(data.player)
            if kramp ~= nil and kramp.components.combat ~= nil then
                kramp.components.combat:SetTarget(data.player)
            end
        end
    end
end

This issue might be due to calling math.random with a parameter of 0.

I found that, if I set krampus to never in my leveldataoverride.lua, TUNING.KRAMPUS_THRESHOLD_VARIANCE will become 0, which is the result of a recent change to worldsettings_overrides.lua.
