Hey there great Miner , thanks for adding Beam . My testing so far (feedback ) workers going offline seems to be different , when I ran 1.3n (cpu usage 80%), my miner ran for 2 days 23 hours then I have the same issue , miner somehow get stuck and goes offline.

Now I'm on 1.3n2 been running for 2 days haven't see any issue  (cpu usage 50%) but I see you have a new release v1.3n3 so I will give it a try

My system below:
i5 6400
16gb ram
Asus mining pro
4 gtx1080
2 rtx2070
3 rx580  running other miner.
Windows 10 Pro
