Nanominer seeing multiple AMD GPU's all of a sudden then closes after 1 minute
I believe AMD updated their drivers and now Nanominer is seeing "2" GPU's for each "1" Physical GPU in the machine. 
It will run then since it can't get hashrate/response from these phantom GPU's will close and restart.   
Rebooted a few times, checked device manager, etc.  All physical GPU's are properly displayed in the OS so its def. nanominer's AMD driver having issues/conflicts with AMD's latest updated driver
