P.S the first step in the full game is to sleep on the 2nd floor of the main building. If you indeed run the full version then you should be able to continue the story by using this bed.
Ah, thank god. The copying of the save files is the most safe way to ensure that everything works smoothly. I wish there was a better way to do this but RPG Maker VXA is a bit of a relic. I apologize for the inconvenience. :3
