I tried reloading the game, starting from a previous save earlier in the playthrough, and just about everything. The only solution that worked was starting over. It wasn't that big of a deal for me since I could pretty much speedrun to that point, but for others that could be a huge problem.
I don't know why this is happening, but I went looking for the coins and consistently, either month 5 or 7 won't have coins. If I get one on 5, I won't find one one 7 and vice versa. I've played through almost 30 times with the same results.
I don't know if this is a bug, or this isn't implemented yet, or if I'm just a smooth brain, but I finished the maze filled with spores but I can't find a way to interact with Lillith.
