Upgraded to 3.20.0 yesterday.
I have RH4 2 x DP8000 and Hog PC running.
Set a fader to full on RH4.
Call a virtual fader window view on Hog PC
All faders go to zero on RH4 and Hog PC
Tried with just Hog PC and DP8000 no RH4. Same result. Soon as you open a Virtual wing window all faders go to zero.
Tried with Full Hog 4 panel open and on screen in Hog PC. Open virtual fader window and all faders to zero.
