1 by 1 obby minigame, not detecting brick touches?

In my game, I have a minigame where each player takes in turns to complete the obby.

If the player falls (or fails), it will touch and invisible brick on the floor, stop their turn, teleport them to the waiting podium, take their name out of a global table and change their team to an other team. If a player completes it, the player will stay on the team and in the table, their score will be increased by 1 and their turn will end.

This is the script;

local replicatedStorage = game:GetService('ReplicatedStorage')
local status = replicatedStorage:WaitForChild('InfoValue')

local inGamers = game.Teams.Players:GetPlayers()

local loops = 0

local MG = game.Workspace.Minigame:FindFirstChild("ObbyMinigame")
local teleTo = MG.TeleportToSpawn
local finishPart = MG.CompletePart
local failPart = MG.FailPart

local spawns = game.Workspace.Minigame:FindFirstChild("ObbyMinigame"):FindFirstChild("Spawns"):GetChildren()
local allspawns = math.random(1, #spawns)
local randomspawn = spawns[allspawns]

repeat
	for i, v in pairs(game.Teams.Players:GetPlayers()) do
		v.Character.Torso.CFrame = CFrame.new(teleTo.Position + Vector3.new(0, 2, 0))
		for t = 30, 1, -1 do
			if t == 1 then
				status.Value = v.Name.." has "..t.." second to complete the obby."
			else
				status.Value = v.Name.." has "..t.." seconds to complete the obby."
			end
			if finishPart.Completed.Value == true then
				local completePlayer = game.Players:FindFirstChild(v.Name)
				completePlayer.Score.Value = completePlayer.Score.Value + 1
				t = 1
				finishPart.Completed.Value = false
				break
			elseif failPart.Failed.Value == true then
				for num, failPlayer in pairs(_G.minigame) do
					if failPlayer == v.Name then
						table.remove(_G.minigame, num)
						v.TeamColor = BrickColor.new('Black')
					end
				end
				t = 1
				failPart.Failed.Value = false
				break
			end
			wait(1)
		end
	end
	loops = loops + 1
until #inGamers <= 1 or loops == 5
script.Disabled = true

In the 'FailPart' and 'CompletePart', I have a BoolValue and a script that does this;

-- In CompletePart
local spawns = game.Workspace.Minigame:FindFirstChild("ObbyMinigame"):FindFirstChild("Spawns"):GetChildren()
local allspawns = math.random(1, #spawns)
local randomspawn = spawns[allspawns]

script.Parent.Touched:connect(function(char)
	script.Parent.Completed.Value = true -- FailPart says 'script.Parent.Failed.Value = true'
	char.Torso.CFrame = CFrame.new(randomspawn.Positon + Vector3.new(0, 5, 0))
end)

No errors in the output.
