17.1.1 on Windows 10 here.
Fairlight Tab:• Master Bus / Bus 1 plugins issue: This is a MAJOR BUG and deserves special attention. Changing the project's timeline resolution, Framerate, Pixel Aspect Ratio, Interlace Processing and Playback frame rate (in short: everything in the Master Settings / Timeline Format menu) will result in a RESET of all Fairlight effects and third-party VST plugins' settings in the Master Bus (Bus 1). This is a serious bug!
Second issue: De-activated FX and Plugins will get activated inadvertently, as well.
Tested with third-party VST plugins (Brainworx, Izotope, Waves). Same effect: All settings reset to default.
In other words: making the changes described above messes up your Master Bus audio plugins.
