I didn't spend a lot of time with Shika n Hana and I completed all the quests.And now the door is broken but I can't repair it(lack of the 2 doorplanks,can't find them in the town or anywhere in the game),Shika n Hana is not in their home，Chocolate's new event can't unlock.What cause this?Is my save stuck?（I asked my friends,they can repair the door,but I can't）
