Why is there an error in the Zednov Tycoon Kit?

I have a problem with the Zednov Tycoon kit, the problem is at line 20, it says that its in infinite yield, I think meaning that it cannot find the button in the PurchasedObjects folder, but I can't find how to fix it!

for i,v in pairs(script.Parent.Buttons:GetChildren()) do
        spawn(function()
        if v:FindFirstChild("Head") then

            local ThingMade = script.Parent.Purchases:WaitForChild(v.Object.Value)
            if ThingMade ~= nil then
                Objects[ThingMade.Name] = ThingMade:Clone()
                ThingMade:Destroy()
            else
                --//Button doesn't have object, remove it
                error('Object missing for button: '..v.Name..', button has been removed')
                v.Head.CanCollide = false
                v.Head.Transparency = 1
            end

            if v:FindFirstChild("Dependency") then --// if button needs something unlocked before it pops up
                v.Head.CanCollide = false
                v.Head.Transparency = 1
                coroutine.resume(coroutine.create(function()
                    if script.Parent.PurchasedObjects:WaitForChild(v.Dependency.Value) then
                        if Settings['ButtonsFadeIn'] then
                            for i=1,20 do
                                wait(Settings['FadeInTime']/20)
                                v.Head.Transparency = v.Head.Transparency - 0.05
                            end
                        end
                        v.Head.CanCollide = true
                        v.Head.Transparency = 0
                    end
                end))
            end
