Exactly. If I update MIX 1, now all I have is MIX 1 and not the original MIX 1 and my current state to compare; I just made my current state be MIX 1, which defeats the point of MIX 1.
And if I didn't update MIX, and all recall options are checked, and I recall MIX 1 for whatever reason, I've just lost all of the work I've done since I created or last updated MIX 1.
This seems like a major security hole. You could lose days or week's worth of work if you did not create a new scene, and then accidentally recalled that first scene for any reason.
It's a tricky scenario, and not addressed in any documentation or video, except to say that you have to have created a new scene before recalling the original one to compare it to.
