Moving parts with a dragging tool sometimes causes parts to un-sync?

Im having an issue while building with a dragging tool I made, for some reason a part might not make joints on the server but will make joints on the client:

client:

capturedsceneP1

server:

capturedsceneP2

tool Localscript:

--values
local debounce = false
local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local tool = script.Parent
local box = Instance.new("SelectionBox")

local selected
local orig	
local dragger
--

function buttondown(mouse)
	local target = mouse.Target
	if target and target:IsA("BasePart") and not target.Locked and
		target:FindFirstChild("PartCore") and target.PartCore:FindFirstChild("Owner") and target.PartCore.Owner.Value == plr.Name then
		if not debounce then
			debounce = true
			selected = target
			dragger = Instance.new("Dragger")
			pcall(function() dragger:MouseDown(selected, Vector3.new(0, 0, 0), {selected}) end)
		box.Adornee = selected
		wait(0.5)-- wait before going again
		debounce = false
		end
	end
end



function buttonup(mouse)
	if dragger then
		local object = mouse.Target
		local sendcfr = selected.CFrame
		script.Parent.MouseUpE:FireServer(object,sendcfr)
		wait()
		orig = nil
		pcall(function() dragger:MouseUp() end)
		box.Adornee = nil
		dragger = nil
	end
end



function mousemove(mouse)
	if dragger then
		pcall(function() dragger:MouseMove(mouse.UnitRay) end)
	end
end




function keymover(key)
	if dragger then
		key = key:lower()
		if key == 'r' then
			dragger:AxisRotate(Enum.Axis.Y)
		elseif key == 't' then
			dragger:AxisRotate(Enum.Axis.Z)
		end
	end
end




function onEquippedLocal(mouse)
	box.Color = BrickColor.new("Lime green")
	box.Parent = plr.PlayerGui

	mouse.Button1Down:connect(function() buttondown(mouse) end)
	mouse.Button1Up:connect(function() buttonup(mouse) end)
	mouse.Move:connect(function() mousemove(mouse) end)
	mouse.KeyDown:connect(keymover)
end






function onUnequippedLocal(mouse)
	if dragger then
		orig = nil
		pcall(function() dragger:MouseUp() end)
		selected = nil
		box.Adornee = nil
		dragger = nil
	end
end


tool.Equipped:connect(onEquippedLocal)
tool.Unequipped:connect(onUnequippedLocal)

ServerScript for tool:

function makechanges(plr,object,cframe)
	

	if object then
		object:BreakJoints()
		object.CFrame = cframe
		object:MakeJoints()
	end
end




script.Parent.MouseUpE.OnServerEvent:Connect(function(plr,object,sendcfr)
	makechanges(plr,object,sendcfr)
end)

sometimes the server/client are synced and other times they de-sync.
is there something I can do to keep the server and client updated on the changes the client makes without hitting or missing on the welds?
