GUI turns invisible, but turns visible after you die?

##Updated And Tested

I think I might have a fix for you. Change it to a Localscript, and try inserting this into it:

Player=game.Players.LocalPlayer --Gets the LocalPlayer

if not Player:FindFirstChild("Visibility") then --Sets up a value that lets the game know to make it visible or not
    Bv = Instance.new("BoolValue",Player)
    Bv.Name = "Visibility"
    Bv.Value = true
end

if Player:FindFirstChild("Visibility").Value == false then
    script.Parent.Parent.Parent.wrathometer.Visible = false
else
    wait(60)
    script.Parent.TextColor3 = Color3.new( 255,0,0 )
    script.Parent.Text = "[ BOSS FIGHT ] Is starting"
    wait(2)
    script.Parent.Text = "[ WARNING ] Boss fight is about to begin!"
    wait(3)
    script.Parent.Parent.Parent.wrathometer.Visible = false
    Player:FindFirstChild("Visibility").Value = false
end

Anyways, the script should work now. Basically, what I did is inserted a value into the player, and whenever the player dies and the script runs again, it checks if the value is true or not, and sets the visiblity depending on that.

Anyways, I hope this makes sense and helped you out a bit. If not or if you have any further problems/questions, please leave a comment below :P

###• It should definitely work now. I have tested it to make sure it does, so if it still isn't working, then something must be wrong with the way you have it settup. Make sure it's in a LocalScript, and everything should work fine
