there is a glitch with the new xmr miner.
No matter what pool you choose, it keeps mining in nanopool as stock setting, and probably stock wallet...
Please check !
Yeah I'm also experiencing the same thing, It's mining away just fine but not to my account.
I agree, after one hour all my workers leave my account.
I return to SGminer 5.5.5
Be careful guys we are mining for some one else with xmr-stak-amd

xtoffm1 and xtoffm2 use SGminer SMOS
xtoffx2 (3 X 1060 6go) xtoffxPC (GTX970) use ccminer windows
the others desappear because of the use of xmr-stak-amd
xtoffx1, xtoffx3, xtoffx4, xtoffx5 and xtoffx6 no more in the list

all my workers at home now

I am waiting for the fix

I hope tu use xmr-stak-amd
