Hi @TheCrazyInsanity . Yes, currently abandoned. The main broken part is the protocol that communicates with Minetest. It was a strange binary protocol to start with, and the dev team made large changes to it without documenting it properly.

If the documentation has been improved, or the protocol replaced by something more sane, the code change would be in https://github.com/boppreh/minetesting/blob/master/client.py .
