Hello,
Unfortunately, we've had to delay the Early Access launch. Our new launch date is March 26th, 2020. We were unhappy with the stability and networking performance of Miner's Mettle entering the final week before launch, and had to make the hard to decision to delay it so it is in good condition during launch.
Thank you for your patience, and we look forward to showing off Miner's Mettle some more to you very soon!
Regards,
Ignatius
