I bought the Zork Anthology a while back (probably a year ago) and first, all the games stopped working. Literally wouldn't launch. So I had to uninstall them all, delete all the content and redownload them. Now the games work again (sadly, my saves are gone); but not all the games are there. I only have 3 Zork titles out of the complete anthology. I've tried going through my gaming collection, tried sorting it in purchase order, etc., but no matter what I do, some of the games are no longer in my library. Anyone else have some phantom Zork games?

Maybe you accidentally hid them. Check the lowest right of your shelf for the "show hidden games" checkbox.

The 'Zork Anthology' installer has 6 games, not 3, check the pic.
