Why is the __nodes table nil in a certain method, but it isn't for another method?

(UPDATE: Everything else, including __nodes, is returning nil)

I am working on a CameraAPI. I am stumped on one thing, though. This used to work before (with the same code), but now it doesn't

I have a CameraApi table. It uses a constructor:

CameraApi:Instantiate()

The module itself calls this constructor on its last line of code

return CameraApi:Instantiate

(NOTE: I use self since CameraApi:Instanstiate() is syntax suguar for CameraApi.Instanstiate(CameraApi); self is an implicit argument which is CameraApi) The constructor returns the following metatable:

return setmetatable(Info, self)

Here's where I go deeper into the problem. In Info, there is a class called Cutscene with the constructor :CreateCutscene with the argument CutsceneName (which is stored in its "Info" table)

Now, I need to explain the functions. It has a __nodestable. It's with two underscores because it is meant to be private.

I use getters(accessors) and setters(mutators) for my Cutscene class

function Info.Cutscene:GetNodes()
    return self.__nodes
end

I have a handy function which changes where the Camera Node faces.

function Info.Cutscene:SetNodeDirection()
    -- ...
end

Whenever I call :GetCameraNodes or print it, it returns nil

(By the way, there is nothing that sets __nodes to nil or something like that)

(Reminder: __nodes is nil in :SetNodeDirection, but not in :GetNodes or outside the module)

(It worked before; is it a bug from roblox?)
