Andesite, Diorite and Granite cobblestone are currently mined in the same way one would punch a cobblestone in vanilla. They take a long time to break, and do not drop anything.

What version of Minecraft and EarlyGame are you using?

EDIT: nvm, it's 1.17. mojank definitely changed how you mine modded blocks ;;

This snapshot release should solve it. Lemme know if you have any more inquiries~
