Try downloading the 0.3.6 patch (Not Update) and 0.3.7 patch, that should fix this bug.
For the 0.3.6 patch, go into the game folder where the exe files is located, delete everything EXCEPT the /game/ folder, that includes the exe files, /lib/ folder, and /renpy/ folder, then extract all files and folder into the Game Folder, where the exe files was located.
For 0.3.7 patch, extract them then put the .rpa files in the folder where all other .rpa files are located. For PC, it's in /GameFolder/game/ For Mac, it's in /GameFolder.app/Content/Resources/autorun/game
Edit : My bad, you're supposed to download 0.3.6 patch, not 0.3.6 update.
