mmpOS has been a solid work horse for the past year or so, it just works!

however earlier this month i started experiencing the same issue as reported by MSF99, disappearing cards, random cards. my initial thoughts was the cards are going bad on me. i have 6 580's all 8GB except one but it turned out it was the issue with phoenix miner and dag file creation was the issue. since version 5e it's been back to normal mostly.

Thanks!
