Making a round-based game but it went sloppy and weird after I tested it?[Self-solved]

[CLOSED BY ME BECAUSE I FOUND A FIX BY C-FRAMING THE CHARACTERS INSTEAD OF LOADING THEM .. Thanks for trying to help me though.]

I can't explain what happened, but here's the script. I don't know if anyone can fix this "confusingness", but it just teleported me everywhere and just did weird stuff with teleporting and loading characters at random times. I can only explain what happened in a video.

plr = script.Parent.Parent.Parent.Parent.Parent
while true do
    local pickRandom = math.random(1, 2)
    script.Parent.Text = "Choosing Map and Waiting for Players."
    wait(20)
    if pickRandom == 1 then
        script.Parent.Text = "Map Chosen: Obby"
        for i,v in pairs(game.Players:GetPlayers()) do
            v.TeamColor = BrickColor.new("Black")
            v:LoadCharacter()
        end
    elseif pickRandom == 2 then
        script.Parent.Text = "Map Chosen: well this is a test soooo.."
        for i,v in pairs(game.Players:GetPlayers()) do
            v.TeamColor = BrickColor.new("Really red")
            v:LoadCharacter()
        end
    end
    wait(100)
    for i,v in pairs(game.Players:GetPlayers()) do
        v.TeamColor = BrickColor.new("White")
    end
end
