When in GUI mode it appears Logic is only recording a snapshot of the Bool/Int controls on transport stop/start. Does not capture changes while running.

So it appears to be a GUI interrupt/thread issue - but only for Bool/Int parameters - and it started with OS Catalina. I am only building 64-bit but is it possible there is still some 32-bit remnant in the iPlug bundle that is causing this?
