Current state / Saved State / Power Off

I’ve just come back to a pattern I created yesterday, and I am confused by it not being at all what I remembered creating.

I DO remember that yesterday I was messing with temp save (combined with ctrl-all) and reload a lot on this track. That was for variations though, I didn’t save that back.

Is it possible that the current state of the pattern (messed up by ctrl-all) got merged into the saved state when I powered off. ? I vaguely remember reading about this kind of stuff but I can’t remember the specifics.

EDIT: The other possibility of course is that I simply messed up.
