This script is crashing my game and I don't know why. Anybody help?

Here is my script:

while true do
	local BrickColo = BrickColor.Random()
	script.Parent.BrickColor = BrickColo
	wait(1)
end

It worked perfectly but then after a few days it just started crashing my game!

Hold on... This script seems to be causing this. When I disable the script up there it still crashes and it blames it on another script... But when I disable this script:

while script.Parent.Value.Value == 1 do
	if script.Parent.ValueA.Value < 5 then
		wait(2)
		local ne = script.Parent.ClonePaer:Clone()
		ne.Parent = script.Parent.Modela
		ne.Anchored = false
		ne.Position = script.Parent.Position
		script.Parent.ValueA.Value = script.Parent.ValueA.Value + 1
	end
end

It all works perfectly.

while wait(1) do
    script.Parent.BrickColor = BrickColor:Random()
end

:)
