Yeah, I can see that an *extended* period of disconnection can be very problematic with the current implementation.
See, details are very important in problem reporting... I was also able to reproduce the problem with scaling after hours of head-scratching.
Hopefully I will push fixes later today.
On a more positive note, remote monitoring with an sgminer-compatible API is coming soon.
I was finally able to have Awesome Miner recognize GGS.
One last thing. Vega 56 arrived at last this afternoon. This means that Vega cards will get the same level of optimizations as RX [45][78]0.
