My Sim will actually 'finish' the book. The book will get to the end and will not complete if I don't have the Sim doing the writing selected. For instance, I have Arya writing a book. I go to Zander to do the gardening. I go back to Arya and she's still writing. I go back and forth, but... if I don't get to Arya by the time she gets to the end of writing the book, the book will not complete. If I try to have her resume writing, she will not resume. She just cancels it out. I have to have her scrap the book and then rewrite the book. As long as I stay selected on her, she will get to the end and the book will actually go through the completion process. I did have it happen once where her father came to talk to her she just stopped writing all together. But I only had that happen once. I wish I could put a door at the top of the stairs so I could lock it while she's writing so no one would talk to her. lol lol Ever since it happened once, I worry it will again. (On PS5 and have every pack).
