I don't get the General Quest: Time spent at most 30m 00s : 1d 11h? what? if I already spend one day how can I get to 0 Secs?
Never mind...just wait and I will answer my questions myself
Hi, it means you spent too much time and need to do a prestige for that feature. If you don't have access to the depth dweller in mining yet, try to reach 40m and look for the upgrade with the same name.
