Documentation issue

The module docstring only mentions the Object typeclass and describes the solution for sharing inheritance that was necessary before ObjectParent was implemented into the game directory.

In addition, the docstring for the Object typeclass itself repeatedly mentions BaseObject, which doesn't exist, and gives what I assume is either a very, very old class path of src.object.objects or is using an unclear shorthand.

Suggested solution

The docstrings should be thoroughly reviewed and updated to match the existing state of evennia
