Oh... that's an interesting interpretation, which would make a lot more sense than the "WFS-speak" Cheshire/Schrodinger's rewards that both do and also do not change at the same time:-P.
I've done SD-148 already, so if you are correct then it looks like I will need to re-do it, and I was thinking that I should hurry to do Time Anti-Spiral as well, to avoid having to do it again a second time, but if I have to do it twice either way, then I suppose I will just wait and not rush:-D.
