Undo thoughts, and an issue with audio track swapping

I think the first step is to get the devs to acknowledge that this is a bug and not a feature request, and possibly not even related to loading a previous state, and if it is, acknowledging that it isn’t working correctly. I don’t think that will happen until someone can post reproducible steps. I have tried to reproduce it several times and nothing, although it has happened to me at least 3 times randomly.
