Regen script breaking after a couple of uses? [FIXED]

It works fine the first few times I use it but then breaks. Anyone have any idea why this could be happening? any help will be appreciated

debounce = true

script.Parent.Touched:connect(function(hit)
    if debounce == false then return end
    if debounce == true then
        debounce = false
    local hum = hit.Parent:FindFirstChild("Humanoid")
        if hum ~= nil then
        local player = game.Players:GetPlayerFromCharacter(hit.Parent)
        local treasure = player.leaderstats.Treasure        
        if treasure.Value == 50 or treasure.Value > 50 then
            treasure.Value = treasure.Value - 50

    local ship = game.ReplicatedStorage.RedShips.Ship1:Clone()
    ship.Parent = game.Workspace.Ships
    ship:MakeJoints()

                    script.Parent.Parent.gp.Transparency = 1
                    script.Parent.Parent.gp.CanCollide = false
                    wait(6)
                    script.Parent.Parent.gp.Transparency = 0
                    script.Parent.Parent.gp.CanCollide = true       

debounce = true
        else
        if debounce == false then debounce = true
        end
        end
        end
        end
end)

edit: Incase anyone wants to know how I solved it I made the script find the humanoid first so a random brick would break it new script:

debounce = true

script.Parent.Touched:connect(function(hit)
        local hum = hit.Parent:FindFirstChild("Humanoid")
        if hum ~= nil then
    if debounce == false then return end
    if debounce == true then
        debounce = false
        local player = game.Players:GetPlayerFromCharacter(hit.Parent)
        if player then
        local treasure = player.leaderstats.Treasure    
        if treasure then    
        if treasure.Value == 50 or treasure.Value > 50 then
            treasure.Value = treasure.Value - 50

    local ship = game.ReplicatedStorage.RedShips.Ship1:Clone()
    ship.Parent = game.Workspace.Ships
    ship:MakeJoints()

                    script.Parent.Parent.gp.Transparency = 1
                    script.Parent.Parent.gp.CanCollide = false
                    wait(6)
                    script.Parent.Parent.gp.Transparency = 0
                    script.Parent.Parent.gp.CanCollide = true       

debounce = true
        else
        if debounce == false then debounce = true
        end
        end
        end
        end
        end
        end
end)
