Timed Mines
Mine areas that refill with blocks on a timer, so they never get stripped bare. Getting into a mine is covered in Mine Time.
How It Works
Each mine is filled mostly with stone and a smaller share of ores. As players dig, its fill percentage drops.
When a mine's timer runs out, the whole area refills with a fresh mix of blocks. You'll see a "resetting" message when it starts and a "reset complete" message when it's done. A mine won't start another reset while one is running.
The Mine Time menu shows each mine's fill percentage and time until its next reset, so you can decide whether to go now or wait for a refill.
