Hi. Thanks for the hard work! just noticed that in these latest releases I can't save render stills from the Live Viewer in PNG8-bit with Alpha (it only works on 16bit PNG). I'm getting black background png images (working on R23). Is this some kind of update? Tested in version 2020.2.3-R2 and it ...

The same is happening to me. Some materials that worked on V4 are crashing on Octane 2020.1. I'll try to provide bug report soon.
