Problem with Runservice stopping as soon as i test

[Evywoe (Evy)]

So, i’ve been trying to write this code so that a bunch of items spawn at designed positions when the character is at a certain distance from the main area part, the thing is, when i hit play to test it out, it either does not run any prints, or runs very few and stops inmediately, i am guessing it’s because of the ammount of things it has to load, since i’m also using runservice.heartbeat for scripts that change transparency and other very simple things.

I also thought it could have been how far the character spawns, but i tested from close to 1000+ stud distance, in both the same thing happened, but again in the smaller scripts with less things to change it worked with no problems.

local cs = game:GetService("CollectionService")
local rs = game:GetService("RunService")

local objs = cs:GetTagged("objspawner")

local zone1 = game.Workspace.Zone1

local plr = game.Players.LocalPlayer

local function spawnparts()
	for i, obj in ipairs(objs) do
		local list = game.ReplicatedStorage.pumpkin:GetChildren()

		local part = list[math.random(1,#list)]


		local par = part:Clone()
		par.Parent = zone1
		par:PivotTo(obj:GetPivot())

	end
end

rs.Heartbeat:Connect(function()
	
	local distance = math.round(plr:DistanceFromCharacter(script.Parent.Position))
	
	print("distance: "..distance)
	
	if distance <= 200 then
		if #zone1:GetChildren() == 0 then
			spawnparts()
			print("function ran")
		else
			
		end
	else
		if #zone1:GetChildren() > 0 then
			for _, pumpk in zone1:GetChildren() do
				pumpk:Destroy()
			end
		end
	end
end)

i am so so dumb, i didn’t realise the part that has the script is unanchored and it keeps falling down the map because it has collissions off!!!
