Hey there, thanks for the report!
The crops will only grow once Common Event 119: Overnight Crop Growth runs. In the full project version of the Wave 1 Bundle, you can get the crops to grow by going inside of the house and using the bed (sorry, I just tested the project out and I should probably make it a lot more obvious that it's the bed event that does this).
This Common Event will also advance to the next day~
Lemme know if that works for you! :D
