Question for Bastep, Ghostship2 and Y-Phil

I'm still having a couple issues rendering with Superfly. I've gone through several of the pages to see if anyone has had the same issues but to no avail. Problem 1 is, there are sparkles (?) or un-render areas (?) within the first picture. You can see them in the arm of the character, cloth and the furniture. I rendered it twice with recommended High settings 10 Pixels with some individual reductions in the Branched Path Tracing selections. My Alienware Processor is an Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz, 2801 Mhz, 4 Core(s), 8 Logical Processor(s)

 The second problem 2 is, one of my characters came out... chocolate? Both female characters are from the same vender Maddelerium, however one of them didn't render properly. 

Any suggestions?
