Active Mining is already much more efficient than AFK mining is. You don’t mine efficient with just one miner and with many miners, you can’t afford to AFK it.
Mining efficiently also means “Rorqual” and suddenly, you are in 0.0 and try to go AFK there. Yes, there are days where you can do it “mostly” AFK, but there are days where AFK mining will net you a lost Rorqual and billions in some excavators.
Even if you use Macks/Retrievers, you lose efficiency. The ones that actually do AFK mining are mining very little m3. I would say forget about it tbh.
Code is also laughable, trying to prevent the poor from picking up breadcrumps. Pathethic.
