CFrame:toObjectSpace() Completely broken

Help and Feedback Scripting Support
#1

Hello, recently, one of my scripts has completely broken. It uses CFrame toObjectSpace and Inverse to move multiple parts (Inside an accessory, so SetPrimaryPartCFrame isn’t possible). Instead of the expected behaviour, it breaks up my models. brokenmodels

It’s causing lots of issues. I really cannot figure out why, as it was working fine yesterday.

It’s not broken. Rarely is a mass-used method like that ever broken. Please show what you’re actually doing instead.

I’ve found a solution. It’s only occurring if I anchor the parts affected. It’s really odd. I’ll make a repro soon.

Edit:

local ShopModules = {}

for _,v in pairs(workspace.Shops:GetChildren()) do
    ShopModules[v.Name] = require(v.Info)
    local TM = ShopModules[v.Name]
    for i,Item in pairs(TM.ItemVisuals) do
        local NewItems = game.ReplicatedStorage.Items[Item.Type][Item.Name]:Clone()
        NewItems.Handle.Anchored = true
        -- oh how do i move all the parts
        local Offset = v.ItemVisuals[tostring(i)].CFrame:toObjectSpace(NewItems.Handle.CFrame)
        for _,x in pairs(NewItems:GetDescendants()) do
            if x:IsA("BasePart") then
                x.Anchored = true
                if Item.Type == "Collector" then
                    x.CFrame *= Offset:Inverse() * CFrame.Angles(math.rad(90),0,math.rad(180))
                else
                    x.CFrame *= Offset:Inverse() * CFrame.Angles(0,math.pi,0)
                end
            end
        end
        NewItems.Parent = v.ItemVisuals
    end
end

This code has the issue.

local ShopModules = {}

for _,v in pairs(workspace.Shops:GetChildren()) do
	ShopModules[v.Name] = require(v.Info)
	local TM = ShopModules[v.Name]
	for i,Item in pairs(TM.ItemVisuals) do
		local NewItems = game.ReplicatedStorage.Items[Item.Type][Item.Name]:Clone()
		
		NewItems.Handle.Anchored = true
		
		local Offset = v.ItemVisuals[tostring(i)].CFrame:Inverse() * NewItems.Handle.CFrame
		
		for _,x in pairs(NewItems:GetDescendants()) do
			if x:IsA("BasePart") then
				if Item.Type == "Collector" then
					x.CFrame *= Offset:Inverse() * CFrame.Angles(math.rad(90),0,math.rad(180))
				else
					x.CFrame *= Offset:Inverse() * CFrame.Angles(0,math.pi,0)
				end
			end
		end
		
		NewItems.Parent = workspace
	end
end

This code does not

The accessories being moved look like this:image
They are welded manually with WeldConstraints.
