(FIXED) [FE] Sword script damage only works in studio but not in a game?

I have a local script that fires a remote event when the tool is activated and a script when the remote event is fired it will damage a NPC. My game is filtering enabled.

Local Script:

local sword = tool:WaitForChild("Sword")
local swordblade = sword:WaitForChild("Blade")
local trail = swordblade:WaitForChild("Trail")
local handle = tool:WaitForChild("Handle")
local swing = handle:WaitForChild("Swing")
local switch = tool:WaitForChild("CanAttack")
local event = tool:WaitForChild("Event")

tool.Equipped:connect(function()
    local idle = script.Parent.Parent.Humanoid:LoadAnimation(script.Idle)
    idle:Play()
end)

tool.Activated:connect(function()
-------------------------------
    event:FireServer() --fires an event in the tool
-------------------------------
    switch.Value = true
    local choose = math.random(1,3)
    if choose == 1 then
        local swing1 = script.Parent.Parent.Humanoid:LoadAnimation(script.Swing1)
        swing1:Play()
        swing:Play()
        trail.Enabled = true
    elseif choose == 2 then
        local swing2 = script.Parent.Parent.Humanoid:LoadAnimation(script.Swing2)
        swing2:Play()
        swing:Play()
        trail.Enabled = true
    elseif choose == 3 then
        local swing3 = script.Parent.Parent.Humanoid:LoadAnimation(script.Swing3)
        swing3:Play()
        swing:Play()
        trail.Enabled = true
    end
end)

tool.Deactivated:connect(function()
    wait(2)
    trail.Enabled = false
    switch.Value = false
end)

tool.Unequipped:connect(function()
    local hum = char:WaitForChild("Humanoid")
    for _,anim in pairs(hum:GetPlayingAnimationTracks()) do
        anim:Stop()
    end
end)

Script:

local tool = script.Parent
local handle = tool:WaitForChild("Handle")
local flesh = handle:WaitForChild("Hit")
local blade = tool:WaitForChild("Blade")
local detect = tool:WaitForChild("CanAttack")
local event = tool:WaitForChild("Event")
-------------------------
event.OnServerEvent:connect(function(plr) --reacts to the remote event being fired
-------------------------
    blade.Touched:connect(function(hit)
        local hum = hit.Parent:FindFirstChild("NPC")
        if hum then
            if detect.Value == true then
                print(hum.Name)
                detect.Value = false
                for i,v in pairs(hit.Parent:GetChildren()) do
                    if v:IsA("IntValue") then
                        v:Destroy()
                    end
                end
                local kill = Instance.new("IntValue",hit.Parent)
                kill.Name = script.Parent.Parent.Name
                detect.Value = false
                flesh:Play()
                hum:TakeDamage(13)
                wait(1)
                detect.Value = true
            end
        end
    end)
end)

I don't understand what is wrong with my scripts as it works in studio but not in a real game and it has no errors.
