VCA Faders resetting; buggy behavior?

I searched the forum and found some old threads about buggy VCA behavior, but nothing recent. In my current project all was working well…until it wasn’t. Without warning my mix “went crazy”. Upon troubleshooting, I found my VCA-linked Tracks had “lost” their starting values and were maxed out like some crazy limiter setting had been applied. The old threads suggest setting a starting value node on the affected tracks as a workaround. Is that still the case? Anyone here using VCAs successfully? Any other suggestions? Is it safer to automate group track levels instead? Thanks…

Bump - insights anyone?
