Description

When StreamingEnabled = true and the CharacterAdded event is connected to a function, if you change the character model’s ModelStreamingMode to Atomic within the function, any GUI element in StarterGui does not get copied to PlayerGui when Players.AutoLoadCharacter = true. Moreover, when the player character dies, it will never respawn.

Reproduction Steps

  1. Create a new place
  2. In the explorer, set Workspace.StreamingEnabled = true
  3. In the explorer, confirm that Players.CharacterAutoLoads = true
  4. In ServerScriptService, create a Script
  5. In the Script, connect a function to Player.CharacterAdded and add a line to change character.ModelStreamingMode = Enum.ModelStreamingMode.Atomic
    Here is a simple example:
function onCharacterAdded(character : Model)
	character.ModelStreamingMode = Enum.ModelStreamingMode.Atomic --Comment this line to fix
end

function onPlayerAdded(player : Player)
	player.CharacterAdded:Connect(onCharacterAdded)
end

game.Players.PlayerAdded:Connect(onPlayerAdded)
  1. Add a ScreenGui and any GuiObject under StarterGui
  2. Press play
  3. No Gui visible. When you reset your character, you will not respawn.

Thanks for the bug report and the repro, we are investigating this issue.

As a workaround if you don’t set the character to be atomic immediately when the character is created you may be able to avoid this problem.
