Nothing is sorting properly!?

I'm trying to make an array loop telling separating Players alive from Dead, only it doesn't seem to work as it only says I've been inserting one Player repeatedly, I ran this in a 3 Player test Server, this is the whole thing

spawn(function()
	while wait() do
		AllPlayers = {}
		for _,Player in pairs(game:GetService("Players"):GetPlayers()) do
			if Player and Player.Character then
				if Player.Character.Humanoid then
					table.insert(AllPlayers, Player)
				end
			end
		end
	end
end)

RegisteredtoLoop = {} --// there is code before this Loop runs, making sure it only sets them before the loop begins, although the code isn't necessary.
for _,Player in pairs(AllPlayers) do
	if Player and Player.Character then
		if Player.Character.Humanoid.Health > 0 then
			table.insert(RegisteredtoLoop, Player)
		end;
	end
end;

local CurrentPlayers = {}; local PlayersDead = {};

while running and runtime ~= 1 do
	for _,Player in pairs(RegisteredtoLoop) do -- Registered gets all the Players from the main loop 'AllPlayers' and puts them in an array for Players who were still alive before the loop started.
	if Player and Player.Character then
		if Player.Character.Humanoid.Health > 0 then
			table.insert(CurrentPlayers, Player)
				print(Player.Name.." was listed as Current."); print(table.concat(CurrentPlayers, " "))
			elseif Player.Character.Humanoid.Health < 1 then
				table.insert(PlayersDead, Player); table.remove(CurrentPlayers, Player)
				print(Player.Name.." was unlisted as Current; PlayerDead");  print(table.concat(CurrentPlayers, " "))
			end
		end
	end;
end;

I can't even print any of them, nothing but userdata errors, what am I doing wrong?
