Forum:Harvest Moon AWL corrupted?

I have been playing HM AWL again lately and have experienced a few things that make me question if the game is corrupted. To start, Van shows up whenever he wants, completely discarding the 3rd and 8th of every month concept. I have seen people report this same problem so I am not sure if it's supposed to happen. Lastly, even after starting a new game some villagers are already my friends, like Nina, Rock and Takakura. I am not suure about takakura becuase I think he is supposed to be your friend. I don't know about Nina or Rock though... Any help is appreciated, I might end up buying a new copy if corruption is the case....
