Last night, version 5.
I left the burial mound without having figured out what the columns were for, and now I’m on the last night and apparently I can’t get back there through the cellar. Can this be salvaged, or am I really going to have to play through a pretty big chunk of the game all over again just to learn two stinking numbers that apparently are only determined when you actually work the puzzle? (I tried going back to an old save and going through the puzzle that way, writing down the hole numbers, then going up to my current save and using those numbers, but no.)
