Player.Team failed because team must be a child of the Teams service triggers falsely

Triggers when a player’s parent is nil and you try to set their Team property, this error is just wrong and confusing (made debugging a lot more difficult).

The following code can reproduce this (ServerScript):

local AssignedTeam = game.Teams.Assigned
--AssignedTeam.Parent = nil

game.Players.PlayerAdded:connect(function(Player)
	
	-- Optional if AssignedTeam.Parent is nil
	-- Both trigger the error
	while Player.Parent do
		wait()
	end
	
	Player.Team = AssignedTeam
end)

Simple repro file if that’s what you need.
