No, working fine here.  Have issues with one card that I will need troubleshoot, but working fine on Nanopool after the fork.

Edit: 18.5.1 driver, OCN settings 1407/910 1100/895, Vega 56 cards (reference -> flashed to 64) + some Sapphire Pulse Vegas 1407/900 960/890.  One card acting up, but the others working fine.  1960/1980 kh/s at 15+14
