Why is my teleportation mismatching?

At the moment, it just currently sends me below the 'baseplate' area and I fall to my death, repeatedly. I've got it to sometimes spawn me at the home spawn.

What i'm TRYING to do is save a players position whenever they leave, and if they die, get sent back to the home.

But anyways, when character is added, it takes the position data and teleports, that should work.

when character is removed however, is where my problem is, i think. I seem to get these bugs that loop myself into confusion. I'm not sure at this point what i'm doing wrong. Point me in the right direction please!

local function onCharacterAdded(character) --Teleport player
    local player = game.Players:GetPlayerFromCharacter(character)
    local data = player:WaitForChild("PlayerData")
    local stats = data:WaitForChild("PlayerStats")

    local TimeJoined = game.Lighting.ClockTime
    character:FindFirstChild("TimeJoined").Value = TimeJoined
    local X = stats.PositionX.Value
    local Y = stats.PositionY.Value
    local Z = stats.PositionZ.Value
    character.HumanoidRootPart.CFrame = CFrame.new(X,Y,Z)
end

local function onCharacterRemoving(character)
    local player = game.Players:GetPlayerFromCharacter(character)
    local data = player:WaitForChild("PlayerData")
    local stats = data:WaitForChild("PlayerStats")
    local birth = stats.Birth.Value
    if character.Death == 1 then --character is dead, changing position data to home.
        local birtharea = workspace:FindFirstChild(birth).Enter
        local spawnX = birtharea.Position.X
        local spawnY = birtharea.Position.Y
        local spawnZ = birtharea.Position.Z

        stats.PositionX.Value = spawnX
        stats.PositionY.Value = spawnY
        stats.PositionZ.Value = spawnZ
        print(birth, stats.PositionX.Value, stats.PositionY.Value, stats.PositionZ.Value)
        stats.Lives.Value = stats.Lives.Value-1
    else --leaving?
        local currentX = character.Head.Position.X
        local currentY = character.Head.Position.Y
        local currentZ = character.Head.Position.Z

        stats.PositionX.Value = currentX
        stats.PositionY.Value = currentY
        stats.PositionZ.Value = currentZ    
    end
end

And my 'setter' code, although not necessary but was mostly a test to see if running it before dying set the position faster, or at all. Honestly, didn't seem to do anything.

local character = script.Parent
if not character then repeat wait() until character end
local player = game.Players:FindFirstChild(character.Name)
local playerData = player:WaitForChild("PlayerData")
local TimeJoined = character:WaitForChild("TimeJoined") 
local Death = character:WaitForChild("Death") 

while wait(.1) do
    if TimeJoined == game.Lighting.ClockTime then
        playerData.PlayerStats.Days.Value = playerData.PlayerStats.Days.Value+1
    end
    if character.Humanoid.Health > 5 then
        wait(1.5)
        Death.Value = 0
    else
        wait(1.5)
        Death.Value = 1
    end
end
