While a program wrapping the overlay glasses is run and it initializes the canvas3d, and .create()s it, if the module is removed, and a line tries to use any of the functions of the object the line will report an error saying:

"A moudle has changed"

I haven't tested if this can happen in other ways, but it had never happened with any other module that I know of.

To be clear, you're reporting the typo and not the fact the error happens, right?
