Never tried the reset button, wasnt sure if Id lose patching. And yes your understanding it correctly. The issue seemed to be following a specific plug in or set of plug ins. I moved/swapped some plugin alliance and UAD plug ins around and the session is now loading correctly. I am on 2020.2.1
Not sure if anybody else has done this but I built a server. Spec is Intel i9 5.0ghz OC, 10c/20t, liquid cooled, rednet PCI. Getting pretty great results with a buffer at 128 @96k. Im running Plugin Alliance, Fab Filter, Kush Audio, Soundtoys, Valhalla, Waves, and UAD with an octo tb3 satellite.
