It is best to contact mrHalfer (Denis) – the author – with this question. As I said before, I am not the developer of this mod. The problem is that it is unknown when mrHalfer will return to development. Perhaps in December.

I appreciate your optimism, Dyrman, but perhaps not everything is lost. But regarding new artifacts, yes, they have already started implementing them.
