I loaded up this afternoon to find my last load still there.  I thought ACE reset, but I have all my pax still from my last flight, and it wasn't saved -- just the same airplane.

Have you tried starting your right engine even after the artificial horizon tilts on GPU?  Worked for me.

Agreed this is a problem.  Might take a little longer than 20 minutes, because I usually start 30 minutes before scheduled departure and push and start five before, but close enough.  I would pay to register FSUPIC if it would fix it.
