Water float bug. one person doesnt float?

Hello, i have a water float script and it works perfectly fine but there is this one person that will not float. Is there a way to fix this? Here is my script:

local runInterval = 1 / 60 local humanoidFloatDamage = 15 local humanoidFloatDamageFrequency = 1.5 --local waterLevel = -12.5

local clippingPlaneDist = 0.5

--------------------------------[[ Running ]]-----------------------------------

local runService = game:GetService("RunService") local player = game.Players.LocalPlayer

local sGui = script.UnserwaterOverlay sGui.Image.Visible = false sGui.Parent = script.Parent.Parent

function newCharacter() local force = Instance.new("BodyPosition") force.D = 6 force.P = 180 local drag = Instance.new("BodyVelocity") drag.velocity = Vector3.new() drag.maxForce = Vector3.new(1, 0, 1) * 100 local dragRot = Instance.new("BodyAngularVelocity") dragRot.maxTorque = Vector3.new(1, 0, 1) * 100 dragRot.angularvelocity = Vector3.new()

local bodyMovers = {force, drag, dragRot}


local character = player.Character or player.CharacterAdded:wait()
local humanoid = player.Character:WaitForChild("Humanoid")
local torso = character:WaitForChild("Torso")
local camera = workspace.CurrentCamera

local mouse = player:GetMouse()

local floating = Instance.new("BoolValue", character)
floating.Name = "Floating"

local lastDamage = 0

local allParts = {}
local _a = {torso, character:WaitForChild("HumanoidRootPart"), character:WaitForChild("Head"), character:WaitForChild("Left Arm"), character:WaitForChild("Right Arm"), character:WaitForChild("Left Leg"), character:WaitForChild("Right Leg")}
for _, v in pairs(_a) do
	table.insert(allParts, {p = v, mass = v:GetMass()})
end

local characterMass = 0
for _, v in pairs(allParts) do
	characterMass = characterMass + v.p:GetMass()
end
local torsoOnly = {{p = torso, mass = characterMass}}
