The Nvidia team was on it and cranked out a new 10.13.6 driver. Linked on our driver page, as well as 10.12.6 security update.
Good news, our EFI eGPU cards still work perfectly as tested on nMP 6,1.
Bad news, the multi Nvidia display screen output bug still in full effect on cMP. I guess we can't hope for a fix until 10.14 Mojave Drivers. Would still love a 10.13.6 fix but then I'm still waiting on a pony for my 7th birthday...
