Is this, seemingly easy to reproduce, thing-y a known issue already?
1. Open a rig in Browse mode
2. Open OUTPUT page 5/6 with 'Pure Cabinet' option
3. Change the rig with Rig Manager
As the RIG changes the 'Pure Cabinet' option changes to 'Rate Preview' option while still in the OUTPUT view.
The Pure cabinet should be visible also after the RM initiated RIG change.
