Game teleports players in studio, but doesn't teleport them in game?

I made a game script but the players don't get teleported to game? Please help! The script is the part that doesn't work. Code doesn't get executed after the teleport script

                    local MapList = Maps:GetChildren()
                    local SelectedIndex = math.random(1,#MapList)
                    local ChosenMap = MapList[SelectedIndex]:Clone()
                    ChosenMap.Parent = workspace
                    wait(10)
                    Sheriffs = Players:GetPlayers() -- Gets all sheriffs
                    local PlayerIndex = math.random(1,#Sheriffs)
                    local JuggernautPlr = Sheriffs[PlayerIndex] 
                    table.remove(Sheriffs,findIndex(Sheriffs,JuggernautPlr))
for i,v in pairs(Sheriffs) do 
                        local NewGun = Gun:Clone()
                        NewGun.Parent = v.Backpack
                        local GameTag = Instance.new("StringValue") -- Used to see if they are in game
                        GameTag.Name = "GameTag"
                        GameTag.Parent = v.Character
                        local Humanoid = v.Character:WaitForChild("Humanoid")
                        local SpawnIndex = math.random(1,#AllSpawns)
                        local ChosenSpawn = AllSpawns[SpawnIndex]
                        Humanoid:MoveTo(ChosenSpawn.Position+Vector3.new(0,3,0)) -- This doesn't work!
                        table.remove(AllSpawns,findIndex(AllSpawns,ChosenSpawn))
                    end
