Here are a few bugs that were brought to my attention, which I fixed in the latest build;
Fixed invisible notes appearing in a later section in the game.
Fixed the appearance of the New Tea Goal Popup for a couple teas.
Fixed the "An Alchemist's Duty" achievement sometimes being granted under wrong conditions.
Fixed a bug where the Bookcase Puzzle could be skipped.
Fixed a bug where clicking the water basin after solving the Bookcase Puzzle skipped into another section of the game.
Thank you for bringing these bugs up to me, if you have any other issues, feel free to inform me!
I hope you continue to play and enjoy my game!
