This is utterly bizarre.
As stated above, last night I rolled back to what I thought was 2016.10
Well I was just helping someone out with a synth problem and noticed that the Synth Tab was no longer in the browser. Imagine my surprise to find it under Views > Synth Rack View
Now my curiosity was totally piqued so I dug a little deeper and according Help > About, I'm running version 22.11.0 Build 111.
All of my plugins are present and correct, including the ones which were causing me grief yesterday.
Could someone with a known, working version confirm what the latest build number is please.
I did adopt the early release the day before if this is a factor.
Interestingly, the CCC shows 2016.10 as a rollback option.
