MainStage 4.3 corrupts volume fader values across patches

Why is it that every time I update MainStage to the latest version, some new and really bizarre bug gets introduced that makes the software unusable on stage?

I’ve been using MainStage for over ten years now, and every single update seems to bring a new issue that eventually forces me to roll back to an older version.

This time it’s the volume faders. On many channel strips across most patches and sets in my concert file, volume faders that should be at 0 dB are automatically being set to −∞ dB. If I move the fader back to 0 dB, save the concert, and then switch between patches, the fader immediately jumps back to −∞ dB. This happens on audio channels and aux channels, but not on the master channels.

I’ve switched back to version 3.7.1 for now, since that’s the last stable version for me.
