This shuts down in online?

I have a script that makes a new pre-set character and it works in studio play solo but not online here is the code:

game.Players.PlayerAdded:connect(function(plr)
    plr.CharacterAdded:wait()
    local modl = game.ServerStorage.Preset:Clone()
    modl.Parent = workspace
    modl:MakeJoints()
    local char = plr.Character
    char:Destroy()
    plr.Character = modl
end)

if game.Workspace:FindFirstChild("Message") then
game.Workspace.Message:Destroy()
end

(it shuts down for some reason)

There may be an external script affecting your game. You should try to check every script to see which one affects the game. You can also try to re-upload the place.
