after map loads, the game won't teleport the players?

local AvailableSpawnPoints = SpawnPoints:GetChildren()

for i, player in pairs(plrs) do
	if player then
		character = player.Character
		
		if character then
			-- teleport them
			
			character:FindFirstChild("HumanoidRootPart").Cframe = AvailableSpawnPoints[1].Cframe
			table.remove(AvailableSpawnPoints,1)

there is 10 spawn points on the map grouped together and stuff btw

Cant you just use Model:MoveTo() ?

in your case it will look like this:

for i, player in pairs(plrs) do
    if player then
        character = player.Character

        if character then
            -- teleport them

            character:MoveTo(AvailableSpawnPoints[1].Position)
            table.remove(AvailableSpawnPoints,1)
