Why is there a mini lag when you get killed by a killingBlock?

Basic Ahh Script for killing when touch.

local killingBricks = script.Parent:GetChildren()

for i, killingBrick in ipairs(killingBricks) do
    if killingBrick:IsA("BasePart") then
        killingBrick.Touched:Connect(function(basePartTouched)
            local humanoid = basePartTouched.Parent:FindFirstChild("Humanoid")
            if humanoid then
                humanoid.Health = 0 
            end
        end)
    end
end

My question is, why when the character dies (humanoid.Health = 0) there's a little lag first?
When I lower its hp to 1, it doesn't lag, it only happens when it dies.

Im highly confident the lag after you die is unrelated to this code, is there any other scripts that do something after the player dies?

Nope

I know, It doesn't have to be with the code

But this also happens on other typical obbies

[sweet vortex]

Then it might be your systems fault because I've never lagged after dying before

But then again I could also be wrong

Imma ask my friends

I don't think I'm the problem

[glossy spade]

alr so

avatar freezes when dying

I don't know why

it isn't a lag

[glossy spade]

ok

It was because of a Roblox bug that had been happening to everyon
