Can I get help fixing a R15 auto-morph script?

So I have been working on a R15 morph for a star wars group. I have been having a problem in which parts of the morphs are oriented weird all at different angles.

Weld Function

local Players = game:GetService('Players')
local Morphs = game:GetService('ServerStorage'):WaitForChild('Morphs')
local Schemes = Morphs.Schemes
local recol = ''
local visible = false
local pack = true
local invis = false
local function MorphUser(User,Team,Class,Morph,name)
    warn("name") 
    local MorphRoot = Morphs[Team][Class]:WaitForChild(Morph)                   
    for _,v in pairs(User.Character:GetChildren()) do
        if v.Name == name then
            v:Destroy()
        end
    end
    local UserMorph = MorphRoot:Clone()
    UserMorph.Parent = User.Character
    UserMorph.Name = name
    if UserMorph:FindFirstChild('Shirt') then
        if User.Character:FindFirstChild('Shirt') then
            User.Character.Shirt:remove()
            UserMorph.Shirt.Parent = User.Character
        end
    end
    if UserMorph:FindFirstChild('Pants') then
        if User.Character:FindFirstChild('Pants') then
            User.Character.Pants:remove()
            UserMorph.Pants.Parent = User.Character
        end
    end
    for _,u in ipairs(UserMorph:GetChildren()) do
        if u.Name ~= 'Shirt' and u.Name ~= 'Pants' then
            --u.Middle.Transparency = 1
            for _,p in ipairs(u:GetChildren()) do
                if p:IsA("BasePart") then
                    local W = Instance.new("Weld",u.Middle)
                    W.Part0 = u.Middle
                    W.Part1 = p
                    local CJ = CFrame.new(u.Middle.Position)
                    local C0 = u.Middle.CFrame:inverse()*CJ
                    local C1 = p.CFrame:inverse()*CJ
                    W.C0 = C0
                    W.C1 = C1
                end
                local Y = Instance.new("Weld",p)
                Y.Part0 = User.Character:FindFirstChild(u.Name)
                Y.Part1 = u.Middle
                Y.C0 = CFrame.new(0, 0, 0)
                p.CanCollide = false
                p.Anchored = false
            end
        end
    end
end

Thing that calls on the weld (This is not the entire thing but it should give you an idea)

--DEV TESTING--
elseif Player.Name == 'EMPTY' then
Morphs.Tools["SE-14C"]:Clone().Parent=Player.Backpack
Morphs.Tools["ISBDetain"]:Clone().Parent=Player.Backpack
Morphs.Tools["Smart Rocket"]:Clone().Parent=Player.Backpack
Morphs.Tools["E-22"]:Clone().Parent=Player.Backpack
MorphUser(Player,"TGE","Enforcement","Dev","Morph")
MorphUser(Player,"Addons","MorphAddons","Hat","Morph1")
Recolour(Character,"NavyGrey")

So a few things happen depending on the morph, it either.

A) doesn't load at all for no apparent reason (I checked output) B) things get flipped around https://gyazo.com/9bfde357a463ed295f8db89e7ac73081 C) it works fine

Any help is much appreciated.
