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
Got screwed too.... not cool.
Be careful when changing miner too, often the change doesn't apply properly and you get mining the stock settings instead of the ones you just set ! loosing all the profit until you notice the zero hashrate at pool.
Always double check after applying.
