MainStage and Plogue Bidule issue

Hi all.

I have a concert with 6 x channel strips at a global level, each with a Bidule plugin hosting a synth plugin (to get around the Playback audio-reset situation) but for some reason, a couple of those channel strips/Bidule instances never "works" (i.e. no sound from the strip) upon loading the concert until I "reset" the channel strip by some means i.e. load the Bidule again, load the channel set settings again etc. As soon as I reset the strip/Bidule, it works.

I have no doubt this is a MainStage issue but have no idea how to troubleshoot. I've tried everything I can think of: removing/re-adding the Bidule, removing/re-adding the channel strip, saving/loading Bidule settings, saving/loading channel strip settings....etc. What's weird is that the issue seems to primarily affect the same 2 channel strips/Bidule instances: after I reset the strip, they will work but if I save/reload the concert, they don't work again! Sometimes, I'll save/reload the concert and one of those 2 strips will work but one of the others (which has always worked) suddenly stops working.

It's almost as if there's some kind of concert corruption that creeps in (but the problems still occur if I rebuild concerts from scratch!!) It's almost as if a MainStage concert craps itself once it reaches a certain level of complexity and it becomes a "falling domino" scenario from that point where you're constantly scrambling to fix one problem after another with no end in sight. This instability is deeply frustrating.

Has anyone else experienced something like this? I've been experiencing a number of seemingly unresolvable, random, illogical issues with MainStage recently (using both v3.1.1 and v3.2.4) and whilst I'm locked into using MS due to my particular requirements, I find myself cursing it on a daily basis.
