ASTRO SPOILER
Not sure if this little markdown thingy will work, but the Lunar Almanac is incorrect. The moon’s shadow actually moves from Right to Left, not left to right as shown in the game.
So, just switch “Waxing” and “Waning” in the Almanac, then the labels of “First Quarter” & “Third Quarter,” and it will be correct!
This means that the Moon code would have to be changed to 2947 rather than 6122.
