ChanCe67T really liked it. He was careful to level up holes he made in passages after digging, then had to quit due to extreme lag. It is much easier to find a place to dig.
Cool! I'm logging in now to check it out! May I suggest on the next reset, to make it Amplified, to see if it's worth it? EDIT: No, I'm not. Auth servers are down. Maybe later... Cheers!
I don't know, Kyukuro has been in there mining! I do know that following a Rif tunnel and digging around it has made me rich.
