Creating Mob Spawner

[trail sparrow]

I am learning and trying to make my own mob spawner where that mob is going to spawn after it dies but...

for some reason, the npc can only spawn once, after that it'll no longer spawns

Code:

More details:

Killed once

Sometimes when it resurrects, it looks like this... sometimes its normal

Killed twice and is no longer respawning...

Ok so i solved the issue myself...

        if spawner then
            local newNPC = npc:Clone()
            local originalPosition = npc.PrimaryPart and npc.PrimaryPart.Position or Vector3.new(0, 0, 0)
            wait(respawnTime)
            npc:Destroy()
            print"Destroying NPC..."
            wait(3)
            local humanoid = newNPC:FindFirstChildOfClass("Humanoid")
            if humanoid then
                humanoid.Died:Connect(function()
                    respawnNPC(npcType, newNPC)
                end)
            end
            humanoid.Health = humanoid.MaxHealth
            newNPC.Parent = workspace.MobNPC[npcType]
            newNPC:MakeJoints()
            newNPC:SetPrimaryPartCFrame(CFrame.new(originalPosition))
            print"Respawned NPC..."
        else warn("Spawn point not found for NPC:", npcType)
        end
