Just checked the new version, and same issue there: miner shuts down after switching from mining devfee (cryptonite on nicehash). This happen on all my rigs. It only works if I leave a few GPUs unchecked on main screen. On my tests it only works on up to 5-GPUs. 6,7,8-GPU configuration doesnt works.
Tested on 5 rigs with AMD RX480/RX580/RX570 using blockchain beta drivers, and crimson 17.7.2 drivers, but same miner behavior, it just limit you to up to 5-GPUs on Cryptonite algo. Seems that Ethereum on Nicehash pool has no this issue all GPUs are usable
