how do i fix this problem while making a npc ai and using body gyros ?

im making a npc ai, and im having a problem that one of the npcs works perfectly fine and the other one just spins like crazy, im using body gyro but it doesn't seems to work ?

here's my code

local crocs = true
local cro = true
local cr = false

local function sue()
    if cr == true then return end
    local timeo = math.random(1,8)
    wait(timeo)
    cro = true
    cr = false
end

function lookAt(chr,target) --assume chr is a character and target is a brick to look towards
    if chr.PrimaryPart then --just make sure the character's HRP has loaded
        local chrPos=chr.PrimaryPart.Position --get the position of the HRP
        local tPos=target.Position --get the position of the target
        local modTPos=Vector3.new(tPos.X,chrPos.Y,tPos.X) --make a position at the target, but with the height of the character
        local newCF=CFrame.new(chrPos,modTPos) --create our CFrame
        chr:SetPrimaryPartCFrame(newCF) --set the HRP's CFrame to our result, thus moving the character!
    end
end

script.Parent.Target.Changed:Connect(function()
    if script.Parent.Target.Value ~= nil then
        crocs = false
        local target = script.Parent.Target.Value
        local myhuam = script.Parent.Humanoid
        while crocs == false do
            wait()
            sue()
            script.Parent.HumanoidRootPart.BodyGyro.CFrame = CFrame.new(script.Parent.Torso.Position - Vector3.new(0,script.Parent.Torso.Position.y,0),target.HumanoidRootPart.Position - Vector3.new(0,target.HumanoidRootPart.Position.y,0))
            --script.Parent.HumanoidRootPart.BodyGyro.CFrame = CFrame.new(script.Parent.Torso.Position - Vector3.new(0,script.Parent.Torso.Position.y,0),target.HumanoidRootPart.Position - Vector3.new(0,target.HumanoidRootPart.Position.y,0))
            cr = true
            local move = math.random(1,3)
            if cro then
            if move < 3 then
                    local moto = math.random(-3,3)
                    local offset = Vector3.new(moto,0,-8)
                local pos = target.Torso.CFrame*CFrame.new(offset).Position
                myhuam:MoveTo(pos)
                end
            end
            if not cro then
                if move == 3 then
                    myhuam:MoveTo(target.Torso.Position)
                end
            end
        end
    else
        crocs = true
    end
end)

and here's a gyazo gif of the problem

the MaxTorque of both body gyros are 0,10000,0 the P is 3000 and the D is 500
