I have a playable game and the script goes
game.Players.CharacterAutoLoads = false local server = script.Parent
note: This isn't the full script and when I enter the game it gets stuck on the Character Loading box
In order for that box to disappear, you have to load the Character at least once. After that, the box will never appear again.
If you want the player to remain character-less, simply Destroy the character immediately after spawning it.
game.Players.PlayerAdded:connect(function(player) player:LoadCharacter() Game.Debris:AddItem(player.Character, 0) end)
