Ideas
My Sim cannot finish a book every time she tries too. This issue was apparently fixed but I am experiencing it much more often than I did previously. I am able to write 1 book after trying & failing to write 5+ books.
My Sim will write until the book is nearly complete then the task just cancels, she does not get distracted or stop on her own. Then when I tell her to continue the book the task appears for a second & she sits at the computer but then the task cancels & disappears, my sim will get a little likes writing bubble appear above her head like she is writing but she is not.
I have tried this save vanilla and it is still happening.
Same thing happening to me. My sim was able to finish books when he was a child but now that he's a teenager he can start a book, get 90% through the task and then it just disappears. Whenever I try to get him to finish it the task appears in the task chart but disappears as soon as it is first in the queue. I uninstalled script mods and repaired my game and he was able to write one book, then the same thing happened - could start book, get 90% through the book and then unable to finish it. No idea what is happening.
