There were some logic related issues with the calendar that I had not considered such as, "What if it is before the previous day of the month but next year?" or "what if it is a previous month but an earlier day?"
Obviously there is a lot that goes into creating a calendar and we appreciate you all being patient with us. We are a tiny team and so testing features to the point of perfection isn't always possible for us.
There were numerous issues with the history system behind the music player that I was unfortunately unaware of and to make it more difficult, the game would stop working instead of showing some sort of error. Along with all that I had planned to take this time to relax and get away from development for just a bit.
Regardless of all that you have all helped me track down and become aware of the crashes so thank you very much. It should all be working now and we hope to hear back from you soon!
