What quests there's left anymore?

Well, maybe problems will occur but I don't care. Have to restart anyway so... But question still open is: What triggers Sandra continuation?
Edit: Come to think of it, I've played this saves' continuum in different versions up and down. 1.5 F+E save in 1.4 Modded and now 1.6.F+E in 1.5.Modded and previously same thing with previous versions. So most probably Corruption is the third name of these saves anyway by now

And no, playing newer version save in older version haven't caused any problems. I think all what changes in Saves is variables which simply don't trigger non-existent content in older versions. Or something.
