Muting issues

I can't tell for sure if this is only in Manchester and/or Lexington but in the last few versions I keep having muted tracks become unmuted, seemingly randomly. For instance often I'll play a temporary bass part and then later on I want to redo it, or try an alternative sound, and I mute the original. Somewhere along the line it'll magically become unmuted and I have two bass parts playing. I have one project where an Addictive Drums instance persistently unmutes itself, although I never actually see it happen, it's just suddenly on again. It's not something I'd automate. Can you even automate a track mute status? In any case, then it'd be regular and predictable.

It seems to often be shortly after saving, is the only thing that springs to mind.

Does anyone else get this and know why?
