A small bug has been found! If you're following the 'Saki Report', after meeting Mirai in the Hotspring, Saki will tell you to see the twins in the evening. Ignore this and meet Celeste in the daytime BEFORE going to the twins. Alternatively, just install the bugfix by extracting the 'game' folder and copying it into your main Falling Stars file. Let it overwrite and you're good to go!
